NAME
       muttrc - Configuration file for the Mutt Mail User Agent

DESCRIPTION
       A  mutt  configuration  file  consists of a series of "commands".  Each
       line of the file may contain one or more commands.  When multiple  com-
       mands are used, they must be separated by a semicolon (";").

       The  hash  mark, or pound sign ("#"), is used as a "comment" character.
       You can use it to annotate your initialization file. All text after the
       comment character to the end of the line is ignored.

       Single  quotes  ("'")  and  double  quotes  (""")  can be used to quote
       strings which contain spaces or other special characters.  The  differ-
       ence between the two types of quotes is similar to that of many popular
       shell programs, namely that a single quote is used to specify a literal
       string (one that is not interpreted for shell variables or quoting with
       a backslash [see next  paragraph]),  while  double  quotes  indicate  a
       string which should be evaluated.  For example, backticks are evaluated
       inside of double quotes, but not single quotes.

       \ quotes the next character, just as in shells such as  bash  and  zsh.
       For  example,  if  want to put quotes (""") inside of a string, you can
       use "\" to force the next character to be a literal instead  of  inter-
       preted character.

       "\\"  means  to insert a literal "\" into the line.  "\n" and "\r" have
       their usual C meanings of linefeed and carriage-return, respectively.

       A "\" at the end of a line can be used to split commands over  multiple
       lines,  provided  that  the  split points don't appear in the middle of
       command names.

       It is also possible to substitute the output of a Unix  command  in  an
       initialization  file.  This is accomplished by enclosing the command in
       backticks (`command`).

       UNIX environment variables can be accessed like the way it is  done  in
       shells  like  sh and bash: Prepend the name of the variable by a dollar
       ("$") sign.

COMMANDS
       alias [-group name [...]] key address [, address [ ... ]]
       unalias [ *  | key ]

              alias defines an alias key for the given addresses. Each address
              will be resolved into either an email address (user@example.com)
              or a named email address  (User  Name  <user@example.com>).  The
              address  may  be  specified  in  either format, or in the format
              "user@example.com (User Name)".  unalias removes the alias  cor-
              responding  to  the given key or all aliases when "*" is used as
              an argument. The optional -group argument to  alias  causes  the
              aliased address(es) to be added to the named group.

       group [-group name] [-rx EXPR [ ... ]] [-addr address [ ... ]]
       ungroup [-group name ] [ * | [[-rx EXPR [ ... ]] [-addr address [ ... ]]]

              group  is  used  to  directly  add  either  addresses or regular
              expressions to the specified group or groups. The different cat-
              egories  of  arguments to the group command can be in any order.
              The flags -rx and -addr specify what the following strings (that
              cannot  begin  with a hyphen) should be interpreted as: either a
              regular expression or an email address,  respectively.   ungroup
              is  used  to  remove  addresses  or regular expressions from the
              specified group or groups. The syntax is similar  to  the  group
              command,  however the special character * can be used to empty a
              group of all of its contents.

              These address groups can  also  be  created  implicitly  by  the
              alias,  lists,  subscribe  and alternates commands by specifying
              the optional -group option.

              Once defined, these address groups can be used  in  patterns  to
              search for and limit the display to messages matching a group.

       alternates [-group name] regexp [ regexp [ ... ]]
       unalternates [ *  | regexp [ regexp [ ... ]] ]

              alternates  is  used  to  inform  mutt about alternate addresses
              where you receive mail; you can use regular expressions to spec-
              ify  alternate  addresses.   This affects mutt's idea about mes-
              sages from you, and messages  addressed  to  you.   unalternates
              removes  a regular expression from the list of known alternates.
              The -group flag causes all of the subsequent regular expressions
              to be added to the named group.

       alternative_order type[/subtype] [ ... ]
       unalternative_order [ *  | type/subtype] [...]

              alternative_order  command  permits  you  to  define an order of
              preference which is used by mutt to determine which  part  of  a
              multipart/alternative body to display.  A subtype of "*" matches
              any subtype, as does  an  empty  subtype.    unalternative_order
              removes entries from the ordered list or deletes the entire list
              when "*" is used as an argument.

       attachments [ + | - ]disposition mime-type
       unattachments [ + | - ]disposition mime-type
       attachments ?
       unattachments *

              attachments specifies what kinds of  attachments  are  used  for
              Mutt's attachment counting and searching support.

              disposition  is  the  attachment's  Content-Disposition  type  -
              either inline or attachment. You can abbreviate this to I or A.

              The first part of a message or multipart group,  if  inline,  is
              counted  separately  than  other inline parts. Specify root or R
              for disposition to count these as  attachments.  If  this  first
              part  is  of type multipart/alternative, note that its top-level
              inline  parts  are  also  counted  via  root   disposition   (if
              $count_alternatives is set).

              disposition  is  prefixed by either a + symbol or a - symbol. If
              it's a +, you're saying that you want to allow this  disposition
              and  MIME  type to qualify. If it's a -, you're saying that this
              disposition and MIME type is an exception to previous + rules.

              mime-type is the MIME type of the attachment you want  the  com-
              mand to affect. A MIME type is always of the format major/minor,
              where major describes the  broad  category  of  document  you're
              looking  at,  and  minor describes the specific type within that
              category. The major part of mime-type must be literal  text  (or
              the  special  token  *),  but  the  minor  part may be a regular
              expression. (Therefore, */.* matches any MIME type.)

              The MIME types you give to the attachments directive are a  kind
              of pattern. When you use the attachments directive, the patterns
              you specify are added to a list. When you use unattachments, the
              pattern  is removed from the list. The patterns are not expanded
              and matched to specific MIME types at this time -  they're  just
              text  in a list. They're only matched when actually evaluating a
              message.

       auto_view type[/subtype] [ ... ]
       unauto_view type[/subtype] [ ... ]

              This commands permits you to specify that mutt should  automati-
              cally convert the given MIME types to text/plain when displaying
              messages.  For this to work, there must be  a  mailcap(5)  entry
              for the given MIME type with the copiousoutput flag set.  A sub-
              type of "*" matches any subtype, as does an empty subtype.

       mime_lookup type[/subtype] [ ... ]
       unmime_lookup type[/subtype] [ ... ]

              This command permits you to define a list of "data" MIME content
              types  for which mutt will try to determine the actual file type
              from the file name, and not use a mailcap(5) entry given for the
              original  MIME  type.   For  instance,  you may add the applica-
              tion/octet-stream MIME type to this list.

       bind map1,map2,... key function
              This command binds the given key for the given map  or  maps  to
              the given function. Multiple maps may be specified by separating
              them with commas (no whitespace is allowed).

              Valid maps are: generic, alias, attach, browser, editor,  index,
              compose, pager, pgp, postpone, mix.

              For  more  information on keys and functions, please consult the
              Mutt Manual. Note that the function  name  is  to  be  specified
              without angle brackets.

       account-hook [!]regexp command
              This hook is executed whenever you access a remote mailbox. Use-
              ful to adjust configuration settings to different  IMAP  or  POP
              servers.

       charset-hook alias charset
              This command defines an alias for a character set.  This is use-
              ful to properly display messages which are tagged with a charac-
              ter set name not known to mutt.

       iconv-hook charset local-charset
              This command defines a system-specific name for a character set.
              This is useful when your system's iconv(3)  implementation  does
              not  understand  MIME  character set names (such as iso-8859-1),
              but instead insists on being  fed  with  implementation-specific
              character  set  names  (such as 8859-1).  In this specific case,
              you'd put this into your configuration file:

              iconv-hook iso-8859-1 8859-1

       message-hook [!]pattern command
              Before mutt displays (or formats for replying or  forwarding)  a
              message which matches the given pattern (or, when it is preceded
              by an exclamation mark, does not match the pattern),  the  given
              command  is  executed.   When multiple message-hooks match, they
              are  executed  in  the order in which they occur in the configu-
              ration file.

       folder-hook [!]regexp command
              When  mutt enters a folder which matches regexp (or, when regexp
              is preceded by an exclamation mark, does not match regexp),  the
              given command is executed.

              When  several  folder-hooks  match a given mail folder, they are
              executed in the order given in the configuration file.

       macro map key sequence [ description ]
              This command binds the given sequence of keys to the  given  key
              in  the given map or maps.  For valid maps, see bind. To specify
              multiple maps, put only a comma between the maps.

       color object [ attribute ... ] foreground background [ regexp ]
       color index [ attribute ... ] foreground background [ pattern ]
       color compose composeobject [ attribute ... ] foreground background
       uncolor index pattern [ pattern ... ]

              If your terminal supports color, these commands can be  used  to
              assign  foreground/background  combinations  to certain objects.
              Valid objects are: attachment, body, bold, error, header, hdrde-
              fault,  index,  indicator,  markers,  message,  normal,  prompt,
              quoted, quotedN, search, signature, status, tilde, tree,  under-
              line.   If the sidebar is enabled the following objects are also
              valid:  sidebar_divider,   sidebar_flagged,   sidebar_highlight,
              sidebar_indicator, sidebar_new, sidebar_spoolfile.  The body and
              header objects allow you to restrict the colorization to a regu-
              lar  expression.  The index object permits you to select colored
              messages by pattern.

              Valid composeobjects  include  header,  security_encrypt,  secu-
              rity_sign, security_both, security_none.

              Valid  colors include: white, black, green, magenta, blue, cyan,
              yellow, red, default, colorN.

              Valid attributes include: none, bold,  underline,  reverse,  and
              standout.

       mono object attribute [ regexp ]
       mono index attribute [ pattern ]

              For  terminals  which  don't support color, you can still assign
              attributes to objects.

       [un]ignore pattern [ pattern ... ]
              The ignore command permits you to specify  header  fields  which
              you  usually  don't  wish  to  see.   Any header field whose tag
              begins with an "ignored" pattern will be ignored.

              The unignore command permits you to define exceptions  from  the
              above mentioned list of ignored headers.

       lists [-group name] regexp [ regexp ... ]
       unlists regexp [ regexp ... ]
       subscribe [-group name] regexp [ regexp ... ]
       unsubscribe regexp [ regexp ... ]

              Mutt  maintains  two  lists  of mailing list address patterns, a
              list of subscribed mailing lists, and a list  of  known  mailing
              lists.   All  subscribed  mailing lists are known.  Patterns use
              regular expressions.

              The lists command adds a mailing list address  to  the  list  of
              known mailing lists.  The unlists command removes a mailing list
              from the lists of known and subscribed mailing lists.  The  sub-
              scribe  command  adds  a  mailing list to the lists of known and
              subscribed mailing lists.  The unsubscribe  command  removes  it
              from  the list of subscribed mailing lists. The -group flag adds
              all of the subsequent regular expressions to the named group.

       mbox-hook [!]regexp mailbox
              When mutt changes to a mail folder which matches regexp, mailbox
              will  be  used as the "mbox" folder, i.e., read messages will be
              moved to that folder when the mail folder is left.

              The first matching mbox-hook applies.

       mailboxes [[-notify | -nonotify]
                  [-poll | -nopoll]
                  [[-label label] | -nolabel]
                  filename] [ ... ]
       unmailboxes [ * | filename ... ]

              The mailboxes specifies folders which can receive mail and which
              will be checked for new messages.  When changing folders, press-
              ing space will cycle through folders with new mail.  The unmail-
              boxes  command  is  used  to remove a file name from the list of
              folders which can receive mail.  If "*" is specified as the file
              name, the list is emptied.

       my_hdr string
       unmy_hdr field

              Using  my_hdr, you can define headers which will be added to the
              messages you compose.  unmy_hdr  will  remove  the  given  user-
              defined headers.

       hdr_order header1 header2 [ ... ]
              With  this  command, you can specify an order in which mutt will
              attempt to present headers to you when viewing messages.

       save-hook [!]pattern filename
              When a message matches pattern, the default file name when  sav-
              ing it will be the given filename.

       fcc-hook [!]pattern filename
              When  an outgoing message matches pattern, the default file name
              for storing a copy (fcc) will be the given filename.

       fcc-save-hook [!]pattern filename
              This command is an abbreviation for identical fcc-hook and save-
              hook commands.

       send-hook [!]pattern command
              When  composing a message matching pattern, command is executed.
              When multiple send-hooks match, they are executed in  the  order
              in which they occur in the configuration file.

       send2-hook [!]pattern command
              Whenever  a message matching pattern is changed (either by edit-
              ing it or by using the compose menu), command is executed.  When
              multiple  send2-hooks  match,  they are executed in the order in
              which they occur in the configuration file.   Possible  applica-
              tions  include  setting  the $sendmail variable when a message's
              from header is changed.

              send2-hook execution is not triggered by  use  of  enter-command
              from the compose menu.

       reply-hook [!]pattern command
              When  replying  to  a  message matching pattern, command is exe-
              cuted.  When multiple reply-hooks match, they  are  executed  in
              the order in which they occur in the configuration file, but all
              reply-hooks are matched and executed before send-hooks,  regard-
              less of their order in the configuration file.

       crypt-hook regexp key-id
              The  crypt-hook command provides a method by which you can spec-
              ify the ID of the public key to be used when encrypting messages
              to  a certain recipient.  The meaning of "key ID" is to be taken
              broadly: This can be a different e-mail address, a numerical key
              ID, or even just an arbitrary search string.  You may use multi-
              ple crypt-hooks with the same regexp; multiple  matching  crypt-
              hooks result in the use of multiple key-ids for a recipient.

       index-format-hook name [!]pattern format-string
              This  command  is used to inject format strings dynamically into
              $index_format based on pattern matching against the current mes-
              sage.

              The  $index_format  expando  %@name@ specifies a placeholder for
              the injection. Index-format-hooks with the same name are matched
              using  pattern  against the current message. Matching is done in
              the order specified in the .muttrc, with the first  match  being
              used.  The  hook's  format-string is then substituted and evalu-
              ated.

       open-hook regexp "command"
       close-hook regexp "command"
       append-hook regexp "command"

              These commands provide a way to handle compressed  folders.  The
              given  regexp  specifies  which  folders are taken as compressed
              (e.g.  "\\.gz$"). The commands tell Mutt  how  to  uncompress  a
              folder  (open-hook),  compress a folder (close-hook) or append a
              compressed mail to a compressed folder (append-hook).  The  com-
              mand  string  is the printf(3) like format string, and it should
              accept two parameters: %f, which  is  replaced  with  the  (com-
              pressed)  folder name, and %t which is replaced with the name of
              the temporary folder to which to write.

       push string
       exec function [ ... ]

              push adds the named string to the keyboard buffer.  "exec  func-
              tion" is equivalent to "push <function>".

       run MuttLisp

              The  run  command evaluates the MuttLisp argument. The output of
              the MuttLisp is then executed as a Mutt command, as if  it  were
              typed in the muttrc instead.

       score pattern value
       unscore [ * | pattern ... ]

              The  score  commands  adds value to a message's score if pattern
              matches it.  The unscore command removes score entries from  the
              list.

       set [no|inv|&|?]variable[=value] [ ... ]
       toggle variable [ ... ]
       unset variable [ ... ]
       reset variable [ ... ]

              These  commands  are  used  to  set and manipulate configuration
              variables.

              Mutt knows four  basic  types  of  variables:  boolean,  number,
              string  and  quadoption.   Boolean  variables can be set (true),
              unset (false), or toggled. Number variables can  be  assigned  a
              positive integer value.

              String  variables consist of any number of printable characters.
              Strings must be enclosed in quotes if  they  contain  spaces  or
              tabs.   You  may also use the "C" escape sequences \n and \t for
              newline and tab, respectively.

              Quadoption variables are used to control whether or  not  to  be
              prompted for certain actions, or to specify a default action.  A
              value of yes will cause the action to be carried  out  automati-
              cally  as if you had answered yes to the question.  Similarly, a
              value of no will cause the action to be carried out  as  if  you
              had answered "no." A value of ask-yes will cause a prompt with a
              default answer of "yes" and ask-no will provide a default answer
              of "no."

              The reset command resets all given variables to the compile time
              defaults.  If you reset the special variable all, all  variables
              will reset to their compile time defaults.

       setenv [?]variable [ value ]
       unsetenv variable

              These  alter  the  environment  that Mutt passes on to its child
              processes.  You can also query  current  environment  values  by
              prefixing a "?" character.

       sidebar_whitelist mailbox [ mailbox ...]
       unsidebar_whitelist [ * | mailbox ... ]

              sidebar_whitelist  specifies  mailboxes that will always be dis-
              played in the sidebar, even if $sidebar_new_mail_only is set and
              the mailbox does not contain new mail.

              unsidebar_whitelist is used to remove a mailbox from the list of
              whitelisted mailboxes. Use unsidebar_whitelist * to  remove  all
              mailboxes.

       source filename
              The given file will be evaluated as a configuration file.

       spam pattern format
       nospam pattern

              These commands define spam-detection patterns from external spam
              filters, so that mutt can sort,  limit,  and  search  on  ``spam
              tags'' or ``spam attributes'', or display them in the index. See
              the Mutt manual for details.

       subjectrx pattern replacement
       unsubjectrx [ * | pattern ]

              subjectrx specifies  a  regular  expression  pattern  which,  if
              detected in a message subject, causes the subject to be replaced
              with the replacement value. The replacement is subject  to  sub-
              stitutions  in  the same way as for the spam command: %L for the
              text to the left of the match, %R for text to the right  of  the
              match,  and %1 for the first subgroup in the match (etc). If you
              simply want to erase the match, set it to "%L%R". Any number  of
              subjectrx commands may coexist.

              Note  this  well: the replacement value replaces the entire sub-
              ject, not just the match!

              unsubjectrx removes a  given  subjectrx  from  the  substitution
              list.  If  *  is  used as the pattern, all substitutions will be
              removed.

       unhook [ *  | hook-type ]
              This command will remove all hooks of a given type, or all hooks
              when  "*"  is  used as an argument.  hook-type can be any of the
              -hook commands documented above.

       mailto_allow header-field [ ... ]
       unmailto_allow [ * | header-field ... ]

              These commands allow the user to  modify  the  list  of  allowed
              header fields in a mailto: URL that Mutt will include in the the
              generated message.  By default the list  contains  only  subject
              and body, as specified by RFC2368.

       echo message
              Prints  message  to  the message window. After printing the mes-
              sage, echo will pause for the number  of  seconds  specified  by
              $sleep_time.

       cd directory
              Changes the current working directory.

PATTERNS
       In various places with mutt, including some of the above mentioned hook
       commands, you can specify patterns to match messages.

   Constructing Patterns
       A simple pattern consists of a modifier of the form "~character",  pos-
       sibly  followed  by a parameter against which mutt is supposed to match
       the object specified by this modifier.  For some characters, the ~  may
       be  replaced  by  another character to alter the behavior of the match.
       These are described in the list of modifiers, below.

       With some of these modifiers, the object to be matched consists of sev-
       eral  e-mail  addresses.   In  these cases, the object is matched if at
       least one of these e-mail addresses matches.  You  can  prepend  a  hat
       ("^")  character  to such a pattern to indicate that all addresses must
       match in order to match the object.

       You can construct complex patterns by combining  simple  patterns  with
       logical  operators.   Logical  AND is specified by simply concatenating
       two simple patterns, for instance "~C mutt-dev ~s bug".  Logical OR  is
       specified  by  inserting a vertical bar ("|") between two patterns, for
       instance "~C mutt-dev | ~s bug".  Additionally, you can negate  a  pat-
       tern  by  prepending a bang ("!") character.  For logical grouping, use
       braces ("()"). Example: "!(~t mutt|~c mutt) ~f elkins".

   Simple Patterns
       Mutt understands the following simple patterns:

       ~A          all messages
       ~b EXPR     messages which contain EXPR in the message body.
       =b STRING   If IMAP is enabled, like ~b but searches for STRING on  the
                   server,  rather than downloading each message and searching
                   it locally.
       ~B EXPR     messages which contain EXPR in the whole message.
       =B STRING   If IMAP is enabled, like ~B but searches for STRING on  the
                   server,  rather than downloading each message and searching
                   it locally.
       ~c EXPR     messages carbon-copied to EXPR
       %c GROUP    messages carbon-copied to any member of GROUP
       ~C EXPR     messages either to: or cc: EXPR
       %C GROUP    messages either to: or cc: to any member of GROUP
       ~d MIN-MAX  messages with "date-sent" in a Date range
       ~D          deleted messages
       ~e EXPR     messages which contain EXPR in the "Sender" field
       %e GROUP    messages which contain a member of GROUP  in  the  "Sender"
                   field
       ~E          expired messages
       ~f EXPR     messages originating from EXPR
       %f GROUP    messages originating from any member of GROUP
       ~F          flagged messages
       ~g          PGP signed messages
       ~G          PGP encrypted messages
       ~h EXPR     messages which contain EXPR in the message header
       =h STRING   If  IMAP is enabled, like ~h but searches for STRING on the
                   server, rather than downloading each message and  searching
                   it locally.  STRING must be of the form "header: substring"
       ~H EXPR     messages with spam tags matching EXPR
       ~i EXPR     messages which match EXPR in the "Message-ID" field
       ~k          messages containing PGP key material
       ~l          messages  addressed  to  a  known  mailing list (defined by
                   either subscribe or list)
       ~L EXPR     messages either originated or received by EXPR
       %L GROUP    messages either originated or received  by  any  member  of
                   GROUP
       ~m MIN-MAX  message in the range MIN to MAX
       ~M EXPR     messages which contain a mime Content-Type matching EXPR
       ~n MIN-MAX  messages with a score in the range MIN to MAX
       ~N          new messages
       ~O          old messages
       ~p          messages  addressed to you (consults $from, alternates, and
                   local account/hostname information)
       ~P          messages from you (consults $from,  alternates,  and  local
                   account/hostname information)
       ~Q          messages which have been replied to
       ~r MIN-MAX  messages with "date-received" in a Date range
       ~R          read messages
       ~s EXPR     messages having EXPR in the "Subject" field.
       ~S          superseded messages
       ~t EXPR     messages addressed to EXPR
       ~T          tagged messages
       ~u          messages addressed to a subscribed mailing list (defined by
                   subscribe commands)
       ~U          unread messages
       ~v          message is part of a collapsed thread.
       ~V          cryptographically verified messages
       ~x EXPR     messages which contain EXPR in  the  "References"  or  "In-
                   Reply-To" field
       ~X MIN-MAX  messages with MIN - MAX attachments
       ~y EXPR     messages which contain EXPR in the "X-Label" field
       ~z MIN-MAX  messages with a size in the range MIN to MAX
       ~=          duplicated messages (see $duplicate_threads)
       ~$          unreferenced message (requires threaded view)
       ~(PATTERN)  messages  in threads containing messages matching a certain
                   pattern, e.g. all threads  containing  messages  from  you:
                   ~(~P)
       ~<(PATTERN) messages  whose  immediate  parent  matches  PATTERN,  e.g.
                   replies to your messages: ~<(~P)
       ~>(PATTERN) messages having an immediate child matching  PATTERN,  e.g.
                   messages you replied to: ~>(~P)

       In the above, EXPR is a regular expression.

       With  the  ~d,  ~m,  ~n, ~r, ~X, and ~z modifiers, you can also specify
       ranges in the forms <MAX, >MIN, MIN-, and -MAX.

       With the ~z modifier, the suffixes "K" and "M" are allowed  to  specify
       kilobyte and megabyte respectively.

       The  ~b,  ~B, ~h, ~M, and ~X modifiers require reading each message in,
       which can be much slower.

       You can force Mutt to treat EXPR as a simple string instead of a  regu-
       lar expression by using = instead of ~ in the pattern name.

   Matching dates
       The ~d and ~r modifiers are used to match date ranges, which are inter-
       preted to be given in your local time zone.

       A date is of the form DD[/MM[/[cc]YY]],  that  is,  a  two-digit  date,
       optionally followed by a two-digit month, optionally followed by a year
       specifications.  Omitted fields default to the current month and year.

       Mutt understands either two or four digit  year  specifications.   When
       given  a  two-digit  year,  mutt  will interpret values less than 70 as
       lying in the 21st century (i.e., "38" means 2038 and not 1938, and "00"
       is  interpreted  as  2000),  and  values greater than or equal to 70 as
       lying in the 20th century.

       Note that this behavior is Y2K compliant, but that  mutt  does  have  a
       Y2.07K problem.

       Alternatively, you may use YYYYMMDD to specify a date.

       If  a  date  range  consists of a single date, the modifier in question
       will match that precise date.  If the date range  consists  of  a  dash
       ("-"), followed by a date, this range will match any date before and up
       to the date given.  Similarly, a date followed by a  dash  matches  the
       date  given  and  any  later  point of time.  Two dates, separated by a
       dash, match any date which lies in the given range of time.

       You can also modify any absolute date by giving  an  error  range.   An
       error  range  consists  of one of the characters +, -, *, followed by a
       positive number, followed by one of the unit characters y, m, w, or  d,
       specifying  a  unit  of years, months, weeks, or days.  + increases the
       maximum date matched by the given interval of  time,  -  decreases  the
       minimum date matched by the given interval of time, and * increases the
       maximum date and decreases the minimum date matched by the given inter-
       val  of  time.   It  is  possible to give multiple error margins, which
       cumulate.  Example: 1/1/2001-1w+2w*3d

       You can also specify offsets relative to the current date.   An  offset
       is  specified  as one of the characters <, >, =, followed by a positive
       number, followed by one of the unit characters y, m, w, d, H, M, or  S.
       >  matches  dates which are older than the specified amount of time, an
       offset which begins with the character < matches dates which  are  more
       recent  than  the  specified amount of time, and an offset which begins
       with the character = matches points of time  which  are  precisely  the
       given amount of time ago.

CONFIGURATION VARIABLES
       abort_noattach
              Type: quadoption
              Default: no

              When  the body of the message matches $abort_noattach_regexp and
              there are no attachments, this quadoption  controls  whether  to
              abort sending the message.



       abort_noattach_regexp
              Type: regular expression
              Default: "attach"

              Specifies  a regular expression to match against the body of the
              message, to determine if an attachment was mentioned but mistak-
              enly  forgotten.   If  it  matches, $abort_noattach will be con-
              sulted to determine if message sending will be aborted.

              Like other regular expressions in Mutt, the search is case  sen-
              sitive  if  the pattern contains at least one upper case letter,
              and case insensitive otherwise.



       abort_nosubject
              Type: quadoption
              Default: ask-yes

              If set to yes, when composing messages and no subject  is  given
              at  the  subject prompt, composition will be aborted.  If set to
              no, composing messages with no  subject  given  at  the  subject
              prompt will never be aborted.



       abort_unmodified
              Type: quadoption
              Default: yes

              If  set to yes, composition will automatically abort after edit-
              ing the message body if no changes are made to  the  file  (this
              check  only happens after the first edit of the file).  When set
              to no, composition will never be aborted.



       alias_file
              Type: path
              Default: "~/.muttrc"

              The default file in which to save aliases created by  the  <cre-
              ate-alias>  function.  Entries added to this file are encoded in
              the character set specified by $config_charset if it is  set  or
              the current character set otherwise.

              Note:  Mutt  will  not  automatically source this file; you must
              explicitly use the "source" command for it  to  be  executed  in
              case this option points to a dedicated alias file.

              The  default  for this option is the currently used muttrc file,
              or "~/.muttrc" if no user muttrc was found.



       alias_format
              Type: string
              Default: "%4n %2f %t %-10a   %r"

              Specifies the format of the data displayed for the "alias" menu.
              The following printf(3)-style sequences are available:
              %a     alias name
              %f     flags - currently, a "d" for an alias marked for deletion
              %n     index number
              %r     address which alias expands to
              %t     character  which  indicates  if  the  alias is tagged for
                     inclusion


       allow_8bit
              Type: boolean
              Default: yes

              Controls whether 8-bit data is converted to 7-bit  using  either
              Quoted- Printable or Base64 encoding when sending mail.



       allow_ansi
              Type: boolean
              Default: no

              Controls whether ANSI color codes in messages (and color tags in
              rich text messages) are to be interpreted.  Messages  containing
              these codes are rare, but if this option is set, their text will
              be colored accordingly. Note that this may override  your  color
              choices,  and  even  present a security problem, since a message
              could include a line like


              [-- PGP output follows ...


              and give it the same color as your attachment  color  (see  also
              $crypt_timestamp).



       arrow_cursor
              Type: boolean
              Default: no

              When  set,  an arrow ("->") will be used to indicate the current
              entry in menus instead of highlighting the whole line.  On  slow
              network  or  modem  links this will make response faster because
              there is less that has to be redrawn on the screen  when  moving
              to the next or previous entries in the menu.



       ascii_chars
              Type: boolean
              Default: no

              If  set,  Mutt  will  use plain ASCII characters when displaying
              thread and attachment trees, instead of the default ACS  charac-
              ters.



       askbcc
              Type: boolean
              Default: no

              If set, Mutt will prompt you for blind-carbon-copy (Bcc) recipi-
              ents before editing an outgoing message.



       askcc
              Type: boolean
              Default: no

              If set, Mutt will prompt you  for  carbon-copy  (Cc)  recipients
              before editing the body of an outgoing message.



       assumed_charset
              Type: string
              Default: ""

              This  variable  is  a colon-separated list of character encoding
              schemes for  messages  without  character  encoding  indication.
              Header  field  values and message body content without character
              encoding indication would be assumed that they  are  written  in
              one of this list.  By default, all the header fields and message
              body without  any  charset  indication  are  assumed  to  be  in
              "us-ascii".

              For example, Japanese users might prefer this:


              set assumed_charset="iso-2022-jp:euc-jp:shift_jis:utf-8"


              However, only the first content is valid for the message body.



       attach_charset
              Type: string
              Default: ""

              This  variable  is  a colon-separated list of character encoding
              schemes for text file attachments. Mutt  uses  this  setting  to
              guess which encoding files being attached are encoded in to con-
              vert them to a proper character set given in $send_charset.

              If unset, the value of $charset will be used instead.  For exam-
              ple,  the  following  configuration would work for Japanese text
              handling:


              set attach_charset="iso-2022-jp:euc-jp:shift_jis:utf-8"


              Note: for Japanese users, "iso-2022-*" must be put at  the  head
              of the value as shown above if included.



       attach_format
              Type: string
              Default: "%u%D%I %t%4n %T%.40d%> [%.7m/%.10M, %.6e%?C?, %C?, %s] "

              This  variable  describes  the  format of the "attachment" menu.
              The following printf(3)-style sequences are understood:
              %C     charset
              %c     requires charset conversion ("n" or "c")
              %D     deleted flag
              %d     description (if none, falls back to %F)
              %e     MIME content-transfer-encoding
              %F     filename in content-disposition header  (if  none,  falls
                     back to %f)
              %f     filename
              %I     disposition ("I" for inline, "A" for attachment)
              %m     major MIME type
              %M     MIME subtype
              %n     attachment number
              %Q     "Q", if MIME part qualifies for attachment counting
              %s     size (see formatstrings-size)
              %t     tagged flag
              %T     graphic tree characters
              %u     unlink (=to delete) flag
              %X     number  of  qualifying  MIME  parts  in this part and its
                     children (please see the "attachments" section for possi-
                     ble speed effects)
              %>X    right justify the rest of the string and pad with charac-
                     ter "X"
              %|X    pad to the end of the line with character "X"
              %*X    soft-fill with character "X" as pad

              For an explanation of "soft-fill", see the  $index_format  docu-
              mentation.



       attach_save_dir
              Type: path
              Default: ""

              The  default directory to save attachments from the "attachment"
              menu.  If it doesn't exist,  Mutt  will  prompt  to  create  the
              directory before saving.

              If  the  path  is  invalid  (e.g.  not a directory, or cannot be
              chdir'ed to), Mutt will fall back to using  the  current  direc-
              tory.



       attach_sep
              Type: string
              Default: "\n"

              The separator to add between attachments when operating (saving,
              printing, piping, etc) on a list of tagged attachments.



       attach_split
              Type: boolean
              Default: yes

              If this variable is unset,  when  operating  (saving,  printing,
              piping, etc) on a list of tagged attachments, Mutt will concate-
              nate the attachments and  will  operate  on  them  as  a  single
              attachment.  The  $attach_sep  separator  is  added  after  each
              attachment. When set, Mutt will operate on the  attachments  one
              by one.



       attribution
              Type: string (localized)
              Default: "On %d, %n wrote:"

              This  is  the  string that will precede a message which has been
              included  in  a  reply.   For  a   full   listing   of   defined
              printf(3)-like sequences see the section on $index_format.



       attribution_locale
              Type: string
              Default: ""

              The  locale  used by strftime(3) to format dates in the attribu-
              tion string.  Legal values are the strings your  system  accepts
              for the locale environment variable $LC_TIME.

              This variable is to allow the attribution date format to be cus-
              tomized by recipient or folder using hooks.   By  default,  Mutt
              will  use  your  locale  environment, so there is no need to set
              this except to override that default.



       auto_subscribe
              Type: boolean
              Default: no

              When set, Mutt assumes the presence of a List-Post header  means
              the  recipient  is  subscribed  to the list.  Unless the mailing
              list is in the "unsubscribe" or "unlist" lists, it will be added
              to  the  "subscribe"  list.   Parsing  and checking these things
              slows header  reading  down,  so  this  option  is  disabled  by
              default.



       auto_tag
              Type: boolean
              Default: no

              When  set,  functions  in  the index menu which affect a message
              will be applied to all tagged messages (if there are any).  When
              unset,  you  must  first use the <tag-prefix> function (bound to
              ";" by default) to make the next function apply  to  all  tagged
              messages.



       autocrypt
              Type: boolean
              Default: no

              When  set,  enables autocrypt, which provides passive encryption
              protection with keys exchanged via headers.  See  "autocryptdoc"
              for more details.  (Autocrypt only)



       autocrypt_acct_format
              Type: string
              Default: "%4n %-30a %20p %10s"

              This  variable  describes  the format of the "autocrypt account"
              menu.  The following printf(3)-style sequences are understood
              %a     email address
              %k     gpg keyid
              %n     current entry number
              %p     prefer-encrypt flag
              %s     status flag (active/inactive)

              (Autocrypt only)



       autocrypt_dir
              Type: path
              Default: "~/.mutt/autocrypt"

              This variable sets where autocrypt files are  stored,  including
              the  GPG  keyring  and  sqlite database.  See "autocryptdoc" for
              more details.  (Autocrypt only)



       autocrypt_reply
              Type: boolean
              Default: yes

              When set, replying to an autocrypt email  automatically  enables
              autocrypt  in  the  reply.  You may want to unset this if you're
              using the same key for autocrypt as normal web-of-trust, so that
              autocrypt isn't forced on for all encrypted replies.  (Autocrypt
              only)



       autoedit
              Type: boolean
              Default: no

              When set along with $edit_headers, Mutt will  skip  the  initial
              send-menu  (prompting  for subject and recipients) and allow you
              to immediately begin editing the  body  of  your  message.   The
              send-menu  may  still be accessed once you have finished editing
              the body of your message.

              Note: when this option is set, you cannot  use  send-hooks  that
              depend  on  the recipients when composing a new (non-reply) mes-
              sage, as the initial list of recipients is empty.

              Also see $fast_reply.



       background_edit
              Type: boolean
              Default: no

              When set, Mutt will run $editor in the background during message
              composition.  A landing page will display, waiting for the $edi-
              tor to exit.  The landing page may be exited,  allowing  perusal
              of  the  mailbox,  or  even  for  other messages to be composed.
              Backgrounded  sessions  may  be  returned  to  via  the   <back-
              ground-compose-menu> function.

              For  background editing to work properly, $editor must be set to
              an editor that does not try to use the Mutt terminal: for  exam-
              ple  a graphical editor, or a script launching (and waiting for)
              the editor in another Gnu Screen window.

              For more details, see "bgedit" ("Background Editing" in the man-
              ual).



       background_confirm_quit
              Type: boolean
              Default: yes

              When set, if there are any background edit sessions, you will be
              prompted to confirm exiting  Mutt,  in  addition  to  the  $quit
              prompt.



       background_format
              Type: string
              Default: "%10S %7p %s"

              This  variable  describes the format of the "background compose"
              menu.  The following printf(3)-style sequences are understood:
              %i     parent message id (for replies and forwarded messages)
              %n     the running number on the menu
              %p     pid of the $editor process
              %r     comma separated list of "To:" recipients
              %R     comma separated list of "Cc:" recipients
              %s     subject of the message
              %S     status of the $editor process: running/finished


       beep
              Type: boolean
              Default: yes

              When this variable is set, mutt will beep when an error occurs.



       beep_new
              Type: boolean
              Default: no

              When this variable is set, mutt will beep whenever it  prints  a
              message  notifying  you of new mail.  This is independent of the
              setting of the $beep variable.



       bounce
              Type: quadoption
              Default: ask-yes

              Controls whether you will be asked to confirm bouncing messages.
              If  set  to yes you don't get asked if you want to bounce a mes-
              sage. Setting this variable to no is not generally  useful,  and
              thus not recommended, because you are unable to bounce messages.



       bounce_delivered
              Type: boolean
              Default: yes

              When  this variable is set, mutt will include Delivered-To head-
              ers when bouncing messages.  Postfix users  may  wish  to  unset
              this variable.



       braille_friendly
              Type: boolean
              Default: no

              When  this  variable  is  set, mutt will place the cursor at the
              beginning  of  the  current  line  in  menus,  even   when   the
              $arrow_cursor variable is unset, making it easier for blind per-
              sons using Braille displays to follow these menus.   The  option
              is  unset  by default because many visual terminals don't permit
              making the cursor invisible.



       browser_abbreviate_mailboxes
              Type: boolean
              Default: yes

              When this variable is set, mutt will abbreviate mailbox names in
              the browser mailbox list, using '~' and '=' shortcuts.

              The  default  "alpha" setting of $sort_browser uses locale-based
              sorting (using  strcoll(3)),  which  ignores  some  punctuation.
              This  can  lead  to some situations where the order doesn't make
              intuitive sense.  In those cases, it may be desirable  to  unset
              this variable.



       browser_sticky_cursor
              Type: boolean
              Default: yes

              When  this variable is set, the browser will attempt to keep the
              cursor on the same mailbox when  performing  various  functions.
              These  include moving up a directory, toggling between mailboxes
              and directory listing,  creating/renaming  a  mailbox,  toggling
              subscribed mailboxes, and entering a new mask.



       certificate_file
              Type: path
              Default: "~/.mutt_certificates"

              This  variable  specifies  the  file  where the certificates you
              trust are saved. When an unknown certificate is encountered, you
              are  asked  if  you accept it or not. If you accept it, the cer-
              tificate can also be saved in this file and further  connections
              are automatically accepted.

              You  can  also  manually  add  CA certificates in this file. Any
              server certificate that is signed with one of these CA  certifi-
              cates is also automatically accepted.

              Example:


              set certificate_file=~/.mutt/certificates




       change_folder_next
              Type: boolean
              Default: no

              When  this variable is set, the <change-folder> function mailbox
              suggestion will start at the next  folder  in  your  "mailboxes"
              list, instead of starting at the first folder in the list.



       charset
              Type: string
              Default: ""

              Character  set  your  terminal uses to display and enter textual
              data.  It is also the fallback for $send_charset.

              Upon startup Mutt tries to derive this  value  from  environment
              variables such as $LC_CTYPE or $LANG.

              Note: It should only be set in case Mutt isn't able to determine
              the character set used correctly.



       check_mbox_size
              Type: boolean
              Default: no

              When this variable is set, mutt will  use  file  size  attribute
              instead  of  access  time when checking for new mail in mbox and
              mmdf folders.

              This variable is unset by default and  should  only  be  enabled
              when  new mail detection for these folder types is unreliable or
              doesn't work.

              Note that enabling this variable should happen before any "mail-
              boxes" directives occur in configuration files regarding mbox or
              mmdf folders because mutt needs to  determine  the  initial  new
              mail  status of such a mailbox by performing a fast mailbox scan
              when it is defined.  Afterwards the new mail status  is  tracked
              by file size changes.



       check_new
              Type: boolean
              Default: yes

              Note: this option only affects maildir and MH style mailboxes.

              When set, Mutt will check for new mail delivered while the mail-
              box is open.  Especially with MH mailboxes, this  operation  can
              take  quite  some  time since it involves scanning the directory
              and checking each file to see if it has already been looked  at.
              If  this  variable  is unset, no check for new mail is performed
              while the mailbox is open.



       collapse_unread
              Type: boolean
              Default: yes

              When unset, Mutt will not collapse a thread if it  contains  any
              unread messages.



       compose_format
              Type: string (localized)
              Default: "-- Mutt: Compose  [Approx. msg size: %l   Atts: %a]%>-"

              Controls  the  format  of the status line displayed in the "com-
              pose" menu.  This string is similar to $status_format,  but  has
              its own set of printf(3)-like sequences:
              %a     total number of attachments
              %h     local hostname
              %l     approximate  size  (in bytes) of the current message (see
                     formatstrings-size)
              %v     Mutt version string

              See the text  describing  the  $status_format  option  for  more
              information on how to set $compose_format.



       config_charset
              Type: string
              Default: ""

              When  defined,  Mutt  will recode commands in rc files from this
              encoding to the current character set as specified  by  $charset
              and  aliases  written  to $alias_file from the current character
              set.

              Please note that if setting $charset it must be done before set-
              ting $config_charset.

              Recoding  should be avoided as it may render unconvertable char-
              acters as question  marks  which  can  lead  to  undesired  side
              effects (for example in regular expressions).



       confirmappend
              Type: boolean
              Default: yes

              When  set, Mutt will prompt for confirmation when appending mes-
              sages to an existing mailbox.



       confirmcreate
              Type: boolean
              Default: yes

              When set, Mutt will prompt for confirmation when saving messages
              to a mailbox which does not yet exist before creating it.



       connect_timeout
              Type: number
              Default: 30

              Causes  Mutt  to  timeout a network connection (for IMAP, POP or
              SMTP) after this many seconds if the connection is not  able  to
              be  established.   A  negative value causes Mutt to wait indefi-
              nitely for the connection attempt to succeed.



       content_type
              Type: string
              Default: "text/plain"

              Sets the default Content-Type for the  body  of  newly  composed
              messages.



       copy
              Type: quadoption
              Default: yes

              This  variable  controls  whether or not copies of your outgoing
              messages will be saved for later references.  Also see  $record,
              $save_name, $force_name and "fcc-hook".



       copy_decode_weed
              Type: boolean
              Default: no

              Controls  whether  Mutt  will  weed  headers  when  invoking the
              <decode-copy> or <decode-save> functions.



       count_alternatives
              Type: boolean
              Default: no

              When set, Mutt will recurse inside multipart/alternatives  while
              performing attachment searching and counting (see attachments).

              Traditionally,  multipart/alternative  parts  have simply repre-
              sented different encodings of the main  content  of  the  email.
              Unfortunately,  some  mail  clients  have started to place email
              attachments inside one of alternatives.  Setting this will allow
              Mutt  to  find  and count matching attachments hidden there, and
              include them in the index via %X or through ~X pattern matching.



       cursor_overlay
              Type: boolean
              Default: no

              When set, Mutt will overlay the indicator,  tree,  sidebar_high-
              light,  and sidebar_indicator colors onto the currently selected
              line.  This will allow default colors in those to be overridden,
              and for attributes to be merged between the layers.



       crypt_autoencrypt
              Type: boolean
              Default: no

              Setting  this  variable will cause Mutt to always attempt to PGP
              encrypt outgoing messages.  This is probably only useful in con-
              nection to the "send-hook" command.  It can be overridden by use
              of the pgp menu, when encryption is not required or  signing  is
              requested as well.  If $smime_is_default is set, then OpenSSL is
              used instead to create S/MIME messages and settings can be over-
              ridden by use of the smime menu instead.  (Crypto only)



       crypt_autopgp
              Type: boolean
              Default: yes

              This  variable  controls  whether  or not mutt may automatically
              enable  PGP   encryption/signing   for   messages.    See   also
              $crypt_autoencrypt,     $crypt_replyencrypt,    $crypt_autosign,
              $crypt_replysign and $smime_is_default.



       crypt_autosign
              Type: boolean
              Default: no

              Setting this variable will cause Mutt to always attempt to cryp-
              tographically sign outgoing messages.  This can be overridden by
              use of the pgp menu, when signing is not required or  encryption
              is  requested as well. If $smime_is_default is set, then OpenSSL
              is used instead to create S/MIME messages and  settings  can  be
              overridden  by  use  of  the smime menu instead of the pgp menu.

       crypt_autosmime
              Type: boolean
              Default: yes

              This variable controls whether or  not  mutt  may  automatically
              enable   S/MIME   encryption/signing   for  messages.  See  also
              $crypt_autoencrypt,    $crypt_replyencrypt,     $crypt_autosign,
              $crypt_replysign and $smime_is_default.



       crypt_confirmhook
              Type: boolean
              Default: yes

              If  set, then you will be prompted for confirmation of keys when
              using the crypt-hook command.  If unset,  no  such  confirmation
              prompt  will be presented.  This is generally considered unsafe,
              especially where typos are concerned.



       crypt_opportunistic_encrypt
              Type: boolean
              Default: no

              Setting this variable will cause Mutt  to  automatically  enable
              and  disable  encryption, based on whether all message recipient
              keys can be located by Mutt.

              When this option is enabled, Mutt will enable/disable encryption
              each  time the TO, CC, and BCC lists are edited.  If $edit_head-
              ers is set, Mutt will also  do  so  each  time  the  message  is
              edited.

              While  this  is  set,  encryption can't be manually enabled/dis-
              abled.  The pgp or smime menus provide a selection to  temporar-
              ily disable this option for the current message.

              If  $crypt_autoencrypt  or $crypt_replyencrypt enable encryption
              for a message, this option will be disabled  for  that  message.
              It  can  be  manually  re-enabled  in  the  pgp  or smime menus.

       crypt_opportunistic_encrypt_strong_keys
              Type: boolean
              Default: no

              When set,  this  modifies  the  behavior  of  $crypt_opportunis-
              tic_encrypt to only search for "strong keys", that is, keys with
              full validity according to the web-of-trust  algorithm.   A  key
              with  marginal  or  no  validity  will  not enable opportunistic
              encryption.

              For S/MIME, the behavior depends on the backend.  Classic S/MIME
              will  filter for certificates with the 't' (trusted) flag in the
              .index file.  The GPGME backend will use  the  same  filters  as
              with  OpenPGP,  and  depends  on GPGME's logic for assigning the
              GPGME_VALIDITY_FULL and GPGME_VALIDITY_ULTIMATE validity flag.



       crypt_protected_headers_read
              Type: boolean
              Default: yes

              When set, Mutt will display protected headers in the pager,  and
              will  update  the  index  and header cache with revised headers.
              Protected headers are stored inside the encrypted or signed part
              of  an  an  email, to prevent disclosure or tampering.  For more
              information see  https://github.com/autocrypt/protected-headers.
              Currently Mutt only supports the Subject header.

              Encrypted  messages using protected headers often substitute the
              exposed Subject header  with  a  dummy  value  (see  $crypt_pro-
              tected_headers_subject).   Mutt  will  update its concept of the
              correct subject after the message is opened, i.e. via the  <dis-
              play-message>  function.  If you reply to a message before open-
              ing it, Mutt will end up using the dummy Subject header,  so  be
              sure to open such a message first.  (Crypto only)



       crypt_protected_headers_save
              Type: boolean
              Default: no

              When  $crypt_protected_headers_read is set, and a message with a
              protected Subject is opened, Mutt will save the updated  Subject
              into  the header cache by default.  This allows searching/limit-
              ing based on the protected Subject  header  if  the  mailbox  is
              re-opened,  without  having  to  re-open  the message each time.
              However, for mbox/mh mailbox types, or if header caching is  not
              set  up,  you  would  need  to re-open the message each time the
              mailbox was reopened before you could see or search/limit on the
              protected subject again.

              When this variable is set, Mutt additionally saves the protected
              Subject back in the clear-text message headers.   This  provides
              better  usability,  but  with  the tradeoff of reduced security.
              The protected Subject header, which  may  have  previously  been
              encrypted,  is  now stored in clear-text in the message headers.
              Copying the message elsewhere, via Mutt or external tools, could
              expose  this  previously  encrypted  data.  Please make sure you
              understand the consequences of this before you enable this vari-
              able.  (Crypto only)



       crypt_protected_headers_subject
              Type: string
              Default: "..."

              When  $crypt_protected_headers_write  is set, and the message is
              marked for encryption, this will be substituted into the Subject
              field  in  the message headers.  To prevent a subject from being
              substituted, unset this variable, or set it to the empty string.
              (Crypto only)



       crypt_protected_headers_write
              Type: boolean
              Default: no

              When  set,  Mutt  will generate protected headers for signed and
              encrypted emails.   Protected  headers  are  stored  inside  the
              encrypted  or  signed part of an an email, to prevent disclosure
              or      tampering.       For      more      information      see
              https://github.com/autocrypt/protected-headers.   Currently Mutt
              only supports the Subject header.  (Crypto only)



       crypt_replyencrypt
              Type: boolean
              Default: yes

              If set, automatically PGP or OpenSSL encrypt replies to messages
              which are encrypted.  (Crypto only)



       crypt_replysign
              Type: boolean
              Default: no

              If  set,  automatically  PGP or OpenSSL sign replies to messages
              which are signed.

              Note: this does not work on  messages  that  are  encrypted  and
              signed!  (Crypto only)



       crypt_replysignencrypted
              Type: boolean
              Default: no

              If  set,  automatically  PGP or OpenSSL sign replies to messages
              which are  encrypted.  This  makes  sense  in  combination  with
              $crypt_replyencrypt,  because it allows you to sign all messages
              which are automatically encrypted.  This works around the  prob-
              lem noted in $crypt_replysign, that mutt is not able to find out
              whether an encrypted message is also signed.  (Crypto only)



       crypt_timestamp
              Type: boolean
              Default: yes

              If set, mutt will include a time stamp in the lines  surrounding
              PGP  or S/MIME output, so spoofing such lines is more difficult.
              If you are using colors to mark these lines, and rely on  these,
              you may unset this setting.  (Crypto only)



       crypt_use_gpgme
              Type: boolean
              Default: no

              This variable controls the use of the GPGME-enabled crypto back-
              ends.  If it is set and Mutt was built with gpgme  support,  the
              gpgme  code for S/MIME and PGP will be used instead of the clas-
              sic code.  Note that you need to set this option in .muttrc;  it
              won't have any effect when used interactively.

              Note  that the GPGME backend does not support creating old-style
              inline (traditional)  PGP  encrypted  or  signed  messages  (see
              $pgp_autoinline).



       crypt_use_pka
              Type: boolean
              Default: no

              Controls       whether       mutt       uses       PKA      (see
              http://www.g10code.de/docs/pka-intro.de.pdf)  during   signature
              verification (only supported by the GPGME backend).



       crypt_verify_sig
              Type: quadoption
              Default: yes

              If "yes", always attempt to verify PGP or S/MIME signatures.  If
              "ask-*", ask whether or not to verify the signature.   If  "no",
              never attempt to verify cryptographic signatures.  (Crypto only)



       date_format
              Type: string
              Default: "!%a, %b %d, %Y at %I:%M:%S%p %Z"

              This  variable  controls  the  format of the date printed by the
              "%d" sequence in $index_format.  This is  passed  to  the  strf-
              time(3)  function  to process the date, see the man page for the
              proper syntax.

              Unless the first character in the string is a  bang  ("!"),  the
              month  and  week day names are expanded according to the locale.
              If the first character in the string is a bang, the bang is dis-
              carded,  and  the  month  and  week day names in the rest of the
              string are expanded in the C locale (that is in US English).



       default_hook
              Type: string
              Default: "~f %s !~P | (~P ~C %s)"

              This variable controls how "message-hook", "reply-hook",  "send-
              hook",  "send2-hook", "save-hook", and "fcc-hook" will be inter-
              preted if they are specified with only a simple regexp,  instead
              of  a  matching  pattern.   The hooks are expanded when they are
              declared, so a hook will be interpreted according to  the  value
              of this variable at the time the hook is declared.

              The  default  value matches if the message is either from a user
              matching the regular expression given, or if it is from you  (if
              the  from  address matches "alternates") and is to or cc'ed to a
              user matching the given regular expression.



       delete
              Type: quadoption
              Default: ask-yes

              Controls whether or not messages are really deleted when closing
              or  synchronizing a mailbox.  If set to yes, messages marked for
              deleting will automatically be purged without prompting.  If set
              to no, messages marked for deletion will be kept in the mailbox.



       delete_untag
              Type: boolean
              Default: yes

              If  this  option  is  set, mutt will untag messages when marking
              them for deletion.  This  applies  when  you  either  explicitly
              delete a message, or when you save it to another folder.



       digest_collapse
              Type: boolean
              Default: yes

              If this option is set, mutt's received-attachments menu will not
              show the subparts of individual messages in a  multipart/digest.
              To see these subparts, press "v" on that menu.



       display_filter
              Type: path
              Default: ""

              When  set,  specifies a command used to filter messages.  When a
              message is viewed it  is  passed  as  standard  input  to  $dis-
              play_filter,  and the filtered message is read from the standard
              output.



       dotlock_program
              Type: path
              Default: "/usr/bin/mutt_dotlock"

              Contains the path of the mutt_dotlock(1) binary to  be  used  by
              mutt.



       dsn_notify
              Type: string
              Default: ""

              This   variable  sets  the  request  for  when  notification  is
              returned.  The string consists of a  comma  separated  list  (no
              spaces!)  of  one  or  more  of  the  following: never, to never
              request notification, failure, to request notification on trans-
              mission  failure,  delay, to be notified of message delays, suc-
              cess, to be notified of successful transmission.

              Example:


              set dsn_notify="failure,delay"


              Note: when using $sendmail for delivery, you should  not  enable
              this  unless you are either using Sendmail 8.8.x or greater or a
              MTA providing a sendmail(1)-compatible interface supporting  the
              -N   option   for   DSN.  For  SMTP  delivery,  DSN  support  is
              auto-detected so that it depends on the server whether DSN  will
              be used or not.



       dsn_return
              Type: string
              Default: ""

              This  variable  controls how much of your message is returned in
              DSN messages.  It may be set to either hdrs to return  just  the
              message header, or full to return the full message.

              Example:


              set dsn_return=hdrs


              Note:  when  using $sendmail for delivery, you should not enable
              this unless you are either using Sendmail 8.8.x or greater or  a
              MTA  providing a sendmail(1)-compatible interface supporting the
              -R  option  for  DSN.  For  SMTP  delivery,   DSN   support   is
              auto-detected  so that it depends on the server whether DSN will
              be used or not.



       duplicate_threads
              Type: boolean
              Default: yes

              This variable controls  whether  mutt,  when  $sort  is  set  to
              threads, threads messages with the same Message-Id together.  If
              it is set, it will indicate that it thinks they  are  duplicates
              of each other with an equals sign in the thread tree.



       edit_headers
              Type: boolean
              Default: no

              This  option allows you to edit the header of your outgoing mes-
              sages along with the body of your message.

              Although the compose menu may have localized header labels,  the
              labels  passed to your editor will be standard RFC 2822 headers,
              (e.g. To:, Cc:, Subject:).  Headers added in  your  editor  must
              also be RFC 2822 headers, or one of the pseudo headers listed in
              "edit-header".   Mutt  will  not  understand  localized   header
              labels, just as it would not when parsing an actual email.

              Note  that changes made to the References: and Date: headers are
              ignored for interoperability reasons.



       editor
              Type: path
              Default: ""

              This variable specifies  which  editor  is  used  by  mutt.   It
              defaults  to  the  value of the $VISUAL, or $EDITOR, environment
              variable, or to the string "vi" if neither of those are set.

              The $editor string may  contain  a  %s  escape,  which  will  be
              replaced by the name of the file to be edited.  If the %s escape
              does not appear in $editor, a space and the name  to  be  edited
              are appended.

              The resulting string is then executed by running


              sh -c 'string'


              where string is the expansion of $editor described above.



       encode_from
              Type: boolean
              Default: no

              When  set,  mutt will quoted-printable encode messages when they
              contain the string "From " (note  the  trailing  space)  in  the
              beginning of a line.  This is useful to avoid the tampering cer-
              tain mail delivery and transport agents tend to do with messages
              (in  order  to  prevent tools from misinterpreting the line as a
              mbox message separator).



       entropy_file
              Type: path
              Default: ""

              The file which includes random data that is used  to  initialize
              SSL library functions.



       envelope_from_address
              Type: e-mail address
              Default: ""

              Manually  sets  the envelope sender for outgoing messages.  This
              value is ignored if $use_envelope_from is unset.



       error_history
              Type: number
              Default: 30

              This variable controls the size (in  number  of  strings  remem-
              bered)  of  the  error messages displayed by mutt.  These can be
              shown with the <error-history> function.  The history is cleared
              each time this variable is set.



       escape
              Type: string
              Default: "~"

              Escape character to use for functions in the built-in editor.



       fast_reply
              Type: boolean
              Default: no

              When  set,  the  initial  prompt  for recipients and subject are
              skipped when replying to messages, and the  initial  prompt  for
              subject is skipped when forwarding messages.

              Note: this variable has no effect when the $autoedit variable is
              set.



       fcc_attach
              Type: quadoption
              Default: yes

              This variable controls whether or not  attachments  on  outgoing
              messages are saved along with the main body of your message.

              Note: $fcc_before_send forces the default (set) behavior of this
              option.



       fcc_before_send
              Type: boolean
              Default: no

              When this variable is set, FCCs will occur  before  sending  the
              message.   Before sending, the message cannot be manipulated, so
              it will be stored  the  exact  same  as  sent:  $fcc_attach  and
              $fcc_clear will be ignored (using their default values).

              When  unset,  the default, FCCs will occur after sending.  Vari-
              ables $fcc_attach and $fcc_clear will be respected, allowing  it
              to  be  stored  without  attachments  or  encryption/signing  if
              desired.



       fcc_clear
              Type: boolean
              Default: no

              When this variable is set, FCCs will be stored  unencrypted  and
              unsigned,  even  when  the  actual  message  is encrypted and/or
              signed.

              Note: $fcc_before_send forces the default  (unset)  behavior  of
              this option.  (PGP only)

              See also $pgp_self_encrypt, $smime_self_encrypt.



       fcc_delimiter
              Type: string
              Default: ""

              When  specified, this allows the ability to Fcc to more than one
              mailbox.  The fcc value will be split by this delimiter and Mutt
              will evaluate each part as a mailbox separately.

              See $record, "fcc-hook", and "fcc-save-hook".



       flag_safe
              Type: boolean
              Default: no

              If set, flagged messages cannot be deleted.



       folder
              Type: path
              Default: "~/Mail"

              Specifies  the default location of your mailboxes.  A "+" or "="
              at the beginning of a pathname will be expanded to the value  of
              this  variable.  Note that if you change this variable (from the
              default) value you need to make sure that the assignment  occurs
              before  you  use "+" or "=" for any other variables since expan-
              sion takes place when handling the "mailboxes" command.



       folder_format
              Type: string
              Default: "%2C %t %N %F %2l %-8.8u %-8.8g %8s %d %f"

              This variable allows you to customize the file  browser  display
              to  your  personal taste.  This string is similar to $index_for-
              mat, but has its own set of printf(3)-like sequences:
              %C     current file number
              %d     date/time folder was last modified
              %D     date/time folder was last modified using $date_format.
              %f     filename ("/" is appended to directory names, "@" to sym-
                     bolic links and "*" to executable files)
              %F     file permissions
              %g     group name (or numeric gid, if missing)
              %l     number of hard links
              %m     number of messages in the mailbox *
              %n     number of unread messages in the mailbox *
              %N     N if mailbox has new mail, blank otherwise
              %s     size in bytes (see formatstrings-size)
              %t     "*" if the file is tagged, blank otherwise
              %u     owner name (or numeric uid, if missing)
              %>X    right justify the rest of the string and pad with charac-
                     ter "X"
              %|X    pad to the end of the line with character "X"
              %*X    soft-fill with character "X" as pad

              For an explanation of "soft-fill", see the  $index_format  docu-
              mentation.

              * = can be optionally printed if nonzero

              %m,  %n,  and %N only work for monitored mailboxes.  %m requires
              $mail_check_stats to be set.  %n requires  $mail_check_stats  to
              be set (except for IMAP mailboxes).



       followup_to
              Type: boolean
              Default: yes

              Controls  whether or not the "Mail-Followup-To:" header field is
              generated when sending mail.  When set, Mutt will generate  this
              field  when  you are replying to a known mailing list, specified
              with the "subscribe" or "lists" commands.

              This field has two purposes.  First, preventing you from receiv-
              ing  duplicate  copies  of replies to messages which you send to
              mailing lists, and second, ensuring that you do get a reply sep-
              arately  for  any  messages sent to known lists to which you are
              not subscribed.

              The header will contain only the list's address  for  subscribed
              lists,  and both the list address and your own email address for
              unsubscribed lists.  Without this header, a group reply to  your
              message  sent to a subscribed list will be sent to both the list
              and your address, resulting in two copies of the same email  for
              you.



       force_name
              Type: boolean
              Default: no

              This  variable  is  similar to $save_name, except that Mutt will
              store a copy of your outgoing message by  the  username  of  the
              address you are sending to even if that mailbox does not exist.

              Also see the $record variable.



       forward_attachments
              Type: quadoption
              Default: ask-yes

              When  forwarding  inline  (i.e.  $mime_forward unset or answered
              with "no" and $forward_decode set), attachments which cannot  be
              decoded  in  a  reasonable  manner will be attached to the newly
              composed message if this quadoption  is  set  or  answered  with
              "yes".



       forward_attribution_intro
              Type: string (localized)
              Default: "----- Forwarded message from %f -----"

              This  is  the  string that will precede a message which has been
              forwarded in the main body of a message (when  $mime_forward  is
              unset).   For a full listing of defined printf(3)-like sequences
              see the section on $index_format.  See also $attribution_locale.



       forward_attribution_trailer
              Type: string (localized)
              Default: "----- End forwarded message -----"

              This is the string that will follow a  message  which  has  been
              forwarded  in  the main body of a message (when $mime_forward is
              unset).  For a full listing of defined printf(3)-like  sequences
              see the section on $index_format.  See also $attribution_locale.



       forward_decode
              Type: boolean
              Default: yes

              Controls  the  decoding of complex MIME messages into text/plain
              when forwarding a message.  The message header is  also  RFC2047
              decoded.  This variable is only used, if $mime_forward is unset,
              otherwise $mime_forward_decode is used instead.



       forward_decrypt
              Type: quadoption
              Default: yes

              This quadoption controls the handling of encrypted messages when
              forwarding  or  attaching  a  message.   When set to or answered
              "yes", the outer layer of encryption is stripped off.

              This variable is used if $mime_forward  is  set  and  $mime_for-
              ward_decode  is unset.  It is also used when attaching a message
              via <attach-message> in the compose menu.  (PGP only)



       forward_edit
              Type: quadoption
              Default: yes

              This quadoption controls whether or not the  user  is  automati-
              cally  placed in the editor when forwarding messages.  For those
              who always want to forward with no modification, use  a  setting
              of "no".



       forward_format
              Type: string
              Default: "[%a: %s]"

              This  variable  controls  the  default subject when forwarding a
              message.  It uses the same format sequences as the $index_format
              variable.



       forward_quote
              Type: boolean
              Default: no

              When  set,  forwarded  messages included in the main body of the
              message (when $mime_forward  is  unset)  will  be  quoted  using
              $indent_string.



       from
              Type: e-mail address
              Default: ""

              When set, this variable contains a default from address.  It can
              be overridden using "my_hdr" (including from a "send-hook")  and
              $reverse_name.  This variable is ignored if $use_from is unset.

              This  setting  defaults to the contents of the environment vari-
              able $EMAIL.



       gecos_mask
              Type: regular expression
              Default: "^[^,]*"

              A regular expression used by mutt to parse the GECOS field of  a
              password entry when expanding the alias.  The default value will
              return the string up to the first "," encountered.  If the GECOS
              field  contains  a  string  like  "lastname, firstname" then you
              should set it to ".*".

              This can be useful  if  you  see  the  following  behavior:  you
              address  an e-mail to user ID "stevef" whose full name is "Steve
              Franklin".    If   mutt   expands   "stevef"   to    ""Franklin"
              stevef@foo.bar" then you should set the $gecos_mask to a regular
              expression that will match the whole name so  mutt  will  expand
              "Franklin" to "Franklin, Steve".



       hdrs
              Type: boolean
              Default: yes

              When  unset,  the  header  fields normally added by the "my_hdr"
              command are not created.  This variable  must  be  unset  before
              composing a new message or replying in order to take effect.  If
              set, the user defined header fields are added to every new  mes-
              sage.



       header
              Type: boolean
              Default: no

              When set, this variable causes Mutt to include the header of the
              message you are replying to into the  edit  buffer.   The  $weed
              setting applies.



       header_cache
              Type: path
              Default: ""

              This  variable points to the header cache database.  If pointing
              to a directory Mutt will contain a header  cache  database  file
              per  folder,  if  pointing  to a file that file will be a single
              global header cache. By default it is unset so no header caching
              will be used.

              Header  caching can greatly improve speed when opening POP, IMAP
              MH or Maildir folders, see "caching" for details.



       header_cache_compress
              Type: boolean
              Default: yes

              When mutt is compiled with qdbm, tokyocabinet,  or  kyotocabinet
              as  header  cache  backend,  this  option determines whether the
              database will be compressed.  Compression  results  in  database
              files  roughly  being  one fifth of the usual diskspace, but the
              decompression can result in a slower opening of cached folder(s)
              which  in  general  is still much faster than opening non header
              cached folders.



       header_cache_pagesize
              Type: number (long)
              Default: 16384

              When mutt is compiled with either gdbm or  bdb4  as  the  header
              cache  backend, this option changes the database page size.  Too
              large or too small values can waste space, memory, or CPU  time.
              The default should be more or less optimal for most use cases.



       header_color_partial
              Type: boolean
              Default: no

              When  set,  color header regexps behave like color body regexps:
              color is applied to the exact text matched by the regexp.   When
              unset, color is applied to the entire header.

              One  use  of  this  option  might  be to apply color to just the
              header labels.

              See "color" for more details.



       help
              Type: boolean
              Default: yes

              When set, help lines describing the bindings for the major func-
              tions  provided  by each menu are displayed on the first line of
              the screen.

              Note: The binding will not be displayed correctly if  the  func-
              tion  is  bound  to  a  sequence rather than a single keystroke.
              Also, the help line may not be updated if a binding  is  changed
              while  Mutt  is running.  Since this variable is primarily aimed
              at new users, neither of these should present a major problem.



       hidden_host
              Type: boolean
              Default: no

              When set, mutt will skip the host name part of  $hostname  vari-
              able  when  adding  the domain part to addresses.  This variable
              does not affect the generation of Message-IDs, and it  will  not
              lead to the cut-off of first-level domains.



       hide_limited
              Type: boolean
              Default: no

              When  set,  mutt will not show the presence of messages that are
              hidden by limiting, in the thread tree.



       hide_missing
              Type: boolean
              Default: yes

              When set, mutt will not show the presence of missing messages in
              the thread tree.



       hide_thread_subject
              Type: boolean
              Default: yes

              When  set,  mutt  will  not  show the subject of messages in the
              thread tree that have the same subject as their parent or  clos-
              est previously displayed sibling.



       hide_top_limited
              Type: boolean
              Default: no

              When  set,  mutt will not show the presence of messages that are
              hidden by limiting, at the top of threads in  the  thread  tree.
              Note  that  when  $hide_limited is set, this option will have no
              effect.



       hide_top_missing
              Type: boolean
              Default: yes

              When set, mutt will not show the presence of missing messages at
              the  top  of  threads  in  the  thread  tree.   Note  that  when
              $hide_missing is set, this option will have no effect.



       history
              Type: number
              Default: 10

              This variable controls the size (in  number  of  strings  remem-
              bered)  of the string history buffer per category. The buffer is
              cleared each time the variable is set.



       history_file
              Type: path
              Default: "~/.mutthistory"

              The file in which Mutt will save its history.

              Also see $save_history.



       history_remove_dups
              Type: boolean
              Default: no

              When set, all of the string history will be scanned  for  dupli-
              cates when a new entry is added.  Duplicate entries in the $his-
              tory_file will also be removed  when  it  is  periodically  com-
              pacted.



       honor_disposition
              Type: boolean
              Default: no

              When  set,  Mutt will not display attachments with a disposition
              of "attachment" inline even if it could render the part to plain
              text.  These  MIME  parts can only be viewed from the attachment
              menu.

              If unset, Mutt will render all MIME parts it can properly trans-
              form to plain text.



       honor_followup_to
              Type: quadoption
              Default: yes

              This  variable controls whether or not a Mail-Followup-To header
              is honored when group-replying to a message.



       hostname
              Type: string
              Default: ""

              Specifies the fully-qualified hostname of  the  system  mutt  is
              running  on  containing  the  host's  name and the DNS domain it
              belongs to. It is used as the domain part (after "@") for  local
              email addresses as well as Message-Id headers.

              Its  value is determined at startup as follows: the node's host-
              name is first determined by the uname(3) function.   The  domain
              is  then  looked  up using the gethostname(2) and getaddrinfo(3)
              functions.  If those calls are unable to determine  the  domain,
              the  full value returned by uname is used.  Optionally, Mutt can
              be compiled with a fixed domain name in which  case  a  detected
              one is not used.

              Starting  in  Mutt 2.0, the operations described in the previous
              paragraph are performed after the muttrc is  processed,  instead
              of  beforehand.   This  way,  if the DNS operations are creating
              delays at startup, you can avoid those by manually  setting  the
              value in your muttrc.

              Also see $use_domain and $hidden_host.



       idn_decode
              Type: boolean
              Default: yes

              When set, Mutt will show you international domain names decoded.
              Note: You can use IDNs for addresses  even  if  this  is  unset.
              This variable only affects decoding. (IDN only)



       idn_encode
              Type: boolean
              Default: yes

              When set, Mutt will encode international domain names using IDN.
              Unset this if your SMTP server can handle newer (RFC 6531) UTF-8
              encoded domains. (IDN only)



       ignore_linear_white_space
              Type: boolean
              Default: no

              This option replaces linear-white-space between encoded-word and
              text to a single space to prevent the  display  of  MIME-encoded
              "Subject:" field from being divided into multiple lines.



       ignore_list_reply_to
              Type: boolean
              Default: no

              Affects  the  behavior  of the <reply> function when replying to
              messages from mailing lists (as defined by  the  "subscribe"  or
              "lists" commands).  When set, if the "Reply-To:" field is set to
              the same value  as  the  "To:"  field,  Mutt  assumes  that  the
              "Reply-To:"  field  was  set  by  the  mailing  list to automate
              responses to the list, and will ignore this field.  To direct  a
              response  to  the  mailing list when this option is set, use the
              <list-reply> function; <group-reply>  will  reply  to  both  the
              sender and the list.



       imap_authenticators
              Type: string
              Default: ""

              This  is  a  colon-delimited list of authentication methods mutt
              may attempt to use to log in to an IMAP  server,  in  the  order
              mutt should try them.  Authentication methods are either "login"
              or the right side of an IMAP "AUTH=xxx" capability string,  e.g.
              "digest-md5", "gssapi" or "cram-md5". This option is case-insen-
              sitive. If it's unset (the default) mutt will try all  available
              methods, in order from most-secure to least-secure.

              Example:


              set imap_authenticators="gssapi:cram-md5:login"


              Note:  Mutt  will only fall back to other authentication methods
              if the previous methods are unavailable. If a method  is  avail-
              able but authentication fails, mutt will not connect to the IMAP
              server.



       imap_check_subscribed
              Type: boolean
              Default: no

              When set, mutt will fetch the set  of  subscribed  folders  from
              your  server on connection, and add them to the set of mailboxes
              it polls for new mail just  as  if  you  had  issued  individual
              "mailboxes" commands.



       imap_condstore
              Type: boolean
              Default: no

              When  set,  mutt  will use the CONDSTORE extension (RFC 7162) if
              advertised by the  server.   Mutt's  current  implementation  is
              basic, used only for initial message fetching and flag updates.

              For  some  IMAP  servers,  enabling  this will slightly speed up
              downloading initial messages.  Unfortunately, Gmail is  not  one
              those,  and  displays  worse  performance  when  enabled.   Your
              mileage may vary.



       imap_deflate
              Type: boolean
              Default: no

              When set, mutt will  use  the  COMPRESS=DEFLATE  extension  (RFC
              4978) if advertised by the server.

              In  general a good compression efficiency can be achieved, which
              speeds up reading large mailboxes also on  fairly  good  connec-
              tions.



       imap_delim_chars
              Type: string
              Default: "/."

              This  contains  the  list  of characters which you would like to
              treat as folder separators for displaying IMAP paths. In partic-
              ular  it  helps  in using the "=" shortcut for your folder vari-
              able.



       imap_fetch_chunk_size
              Type: number (long)
              Default: 0

              When set to a value greater than 0, new headers  will  be  down-
              loaded  in groups of this many headers per request.  If you have
              a very large mailbox, this might prevent a timeout  and  discon-
              nect  when  opening  the  mailbox, by sending a FETCH per set of
              this many headers, instead of a single FETCH for all  new  head-
              ers.



       imap_headers
              Type: string
              Default: ""

              Mutt  requests  these  header  fields in addition to the default
              headers ("Date:", "From:", "Sender:", "Subject:", "To:",  "Cc:",
              "Message-Id:", "References:", "Content-Type:", "Content-Descrip-
              tion:",  "In-Reply-To:",  "Reply-To:",  "Lines:",  "List-Post:",
              "X-Label:")  from IMAP servers before displaying the index menu.
              You may want to add more headers for spam detection.

              Note: This is a space separated list, items should be  uppercase
              and  not  contain the colon, e.g. "X-BOGOSITY X-SPAM-STATUS" for
              the "X-Bogosity:" and "X-Spam-Status:" header fields.



       imap_idle
              Type: boolean
              Default: no

              When set, mutt will attempt to use the IMAP  IDLE  extension  to
              check for new mail in the current mailbox. Some servers (dovecot
              was the inspiration for  this  option)  react  badly  to  mutt's
              implementation.  If  your connection seems to freeze up periodi-
              cally, try unsetting this.



       imap_keepalive
              Type: number
              Default: 300

              This variable specifies the maximum amount of  time  in  seconds
              that  mutt  will  wait  before polling open IMAP connections, to
              prevent the server from closing them before  mutt  has  finished
              with  them. The default is well within the RFC-specified minimum
              amount of time (30 minutes) before a server  is  allowed  to  do
              this,  but  in  practice the RFC does get violated every now and
              then. Reduce this number if you find  yourself  getting  discon-
              nected from your IMAP server due to inactivity.



       imap_list_subscribed
              Type: boolean
              Default: no

              This  variable configures whether IMAP folder browsing will look
              for only subscribed folders or all folders.  This can be toggled
              in the IMAP browser with the <toggle-subscribed> function.



       imap_login
              Type: string
              Default: ""

              Your login name on the IMAP server.

              This variable defaults to the value of $imap_user.



       imap_oauth_refresh_command
              Type: string
              Default: ""

              The command to run to generate an OAUTH refresh token for autho-
              rizing your connection to your IMAP server.  This  command  will
              be  run  on  every  connection attempt that uses the OAUTHBEARER
              authentication mechanism.  See "oauth" for details.



       imap_pass
              Type: string
              Default: ""

              Specifies the password for your IMAP account.   If  unset,  Mutt
              will   prompt   you  for  your  password  when  you  invoke  the
              <imap-fetch-mail> function or try to open an IMAP folder.

              Warning: you should only use this  option  when  you  are  on  a
              fairly  secure machine, because the superuser can read your mut-
              trc even if you are the only one who can read the file.



       imap_passive
              Type: boolean
              Default: yes

              When set, mutt will not open new IMAP connections to  check  for
              new  mail.  Mutt will only check for new mail over existing IMAP
              connections.  This is useful if you don't want  to  be  prompted
              for  user/password  pairs  on mutt invocation, or if opening the
              connection is slow.



       imap_peek
              Type: boolean
              Default: yes

              When set, mutt will avoid implicitly marking your mail  as  read
              whenever  you fetch a message from the server. This is generally
              a good thing, but can  make  closing  an  IMAP  folder  somewhat
              slower. This option exists to appease speed freaks.



       imap_pipeline_depth
              Type: number
              Default: 15

              Controls  the  number  of  IMAP  commands  that may be queued up
              before they are sent to the server. A  deeper  pipeline  reduces
              the  amount  of time mutt must wait for the server, and can make
              IMAP servers feel much more responsive. But not all servers cor-
              rectly  handle  pipelined  commands, so if you have problems you
              might want to try setting this variable to 0.

              Note: Changes to this variable have no effect  on  open  connec-
              tions.



       imap_poll_timeout
              Type: number
              Default: 15

              This  variable  specifies  the maximum amount of time in seconds
              that mutt will wait for a response when polling IMAP connections
              for new mail, before timing out and closing the connection.  Set
              to 0 to disable timing out.



       imap_qresync
              Type: boolean
              Default: no

              When set, mutt will use the  QRESYNC  extension  (RFC  7162)  if
              advertised  by  the  server.   Mutt's  current implementation is
              basic, used only for initial message fetching and flag updates.

              Note: this feature is currently experimental.  If you experience
              strange  behavior,  such as duplicate or missing messages please
              file a bug report to let us know.



       imap_servernoise
              Type: boolean
              Default: yes

              When set, mutt will  display  warning  messages  from  the  IMAP
              server  as  error messages. Since these messages are often harm-
              less, or generated due to configuration problems on  the  server
              which are out of the users' hands, you may wish to suppress them
              at some point.



       imap_user
              Type: string
              Default: ""

              The name of the user whose mail you intend to access on the IMAP
              server.

              This variable defaults to your user name on the local machine.



       implicit_autoview
              Type: boolean
              Default: no

              If  set  to  "yes",  mutt will look for a mailcap entry with the
              "copiousoutput" flag set for every MIME  attachment  it  doesn't
              have an internal viewer defined for.  If such an entry is found,
              mutt will use the viewer defined in that entry  to  convert  the
              body part to text form.



       include
              Type: quadoption
              Default: ask-yes

              Controls  whether or not a copy of the message(s) you are reply-
              ing to is included in your reply.



       include_encrypted
              Type: boolean
              Default: no

              Controls whether  or  not  Mutt  includes  separately  encrypted
              attachment contents when replying.

              This  variable  was  added  to  prevent  accidental  exposure of
              encrypted contents when replying to an attacker.   If  a  previ-
              ously  encrypted  message  were  attached  by the attacker, they
              could trick an unwary recipient into  decrypting  and  including
              the message in their reply.



       include_onlyfirst
              Type: boolean
              Default: no

              Controls  whether or not Mutt includes only the first attachment
              of the message you are replying.



       indent_string
              Type: string
              Default: "> "

              Specifies the string to prepend to each line of text quoted in a
              message  to which you are replying.  You are strongly encouraged
              not to change this value, as it tends to agitate the more fanat-
              ical netizens.

              The  value  of  this  option  is ignored if $text_flowed is set,
              because the quoting  mechanism  is  strictly  defined  for  for-
              mat=flowed.

              This  option  is  a format string, please see the description of
              $index_format for supported printf(3)-style sequences.



       index_format
              Type: string
              Default: "%4C %Z %{%b %d} %-15.15L (%?l?%4l&%4c?) %s"

              This variable allows you to customize the message index  display
              to your personal taste.

              "Format  strings" are similar to the strings used in the C func-
              tion printf(3) to format output  (see  the  man  page  for  more
              details).  For an explanation of the %? construct, see the $sta-
              tus_format description.  The following sequences are defined  in
              Mutt:
              %a     address of the author
              %A     reply-to  address  (if  present;  otherwise:  address  of
                     author)
              %b     filename of the original message folder (think mailbox)
              %B     the list to which the letter was sent, or else the folder
                     name (%b).
              %c     number  of characters (bytes) in the message (see format-
                     strings-size)
              %C     current message number
              %d     date and time of the message in the format  specified  by
                     $date_format converted to sender's time zone
              %D     date  and  time of the message in the format specified by
                     $date_format converted to the local time zone
              %e     current message number in thread
              %E     number of messages in current thread
              %f     sender  (address  +   real   name),   either   From:   or
                     Return-Path:
              %F     author name, or recipient name if the message is from you
              %H     spam attribute(s) of this message
              %i     message-id of the current message
              %l     number  of lines in the unprocessed message (may not work
                     with maildir, mh, and IMAP folders)
              %L     If an address in the "To:" or "Cc:" header field  matches
                     an address defined by the users "subscribe" command, this
                     displays "To <list-name>", otherwise the same as %F.
              %m     total number of message in the mailbox
              %M     number of hidden messages if the thread is collapsed.
              %N     message score
              %n     author's real name (or address if missing)
              %O     original save  folder  where  mutt  would  formerly  have
                     stashed  the  message: list name or recipient name if not
                     sent to a list
              %P     progress indicator for the built-in pager  (how  much  of
                     the file has been displayed)
              %r     comma separated list of "To:" recipients
              %R     comma separated list of "Cc:" recipients
              %s     subject of the message
              %S     single     character     status     of     the    message
                     ("N"/"O"/"D"/"d"/"!"/"r"/"*")
              %t     "To:" field (recipients)
              %T     the appropriate character from the $to_chars string
              %u     user (login) name of the author
              %v     first name of the author, or the recipient if the message

              %Y     "X-Label:" field, if present, and (1) not at  part  of  a
                     thread  tree,  (2)  at  the  top  of  a  thread,  or  (3)
                     "X-Label:"  is   different   from   preceding   message's
                     "X-Label:".
              %Z     a three character set of message status flags.  the first
                     character        is        new/read/replied         flags
                     ("n"/"o"/"r"/"O"/"N").   the second is deleted or encryp-
                     tion  flags  ("D"/"d"/"S"/"P"/"s"/"K").   the  third   is
                     either tagged/flagged ("*"/"!"), or one of the characters
                     listed in $to_chars.

              %[fmt] the  date  and  time  of  the message is converted to the

              %>X    right justify the rest of the string and pad with charac-
                     ter "X"
              %|X    pad to the end of the line with character "X"
              %*X    soft-fill with character "X" as pad

              Note  that  for  mbox/mmdf, "%l" applies to the unprocessed mes-
              sage, and for maildir/mh, the  value  comes  from  the  "Lines:"
              header  field  when  present (the meaning is normally the same).
              Thus the value depends on the encodings used  in  the  different
              parts of the message and has little meaning in practice.

              "Soft-fill"  deserves  some explanation: Normal right-justifica-
              tion will print everything to the left of the  "%>",  displaying
              padding  and whatever lies to the right only if there's room. By
              contrast, soft-fill gives priority to the right-hand side, guar-
              anteeing space to display it and showing padding only if there's
              still room. If necessary, soft-fill will eat text  leftwards  to
              make room for rightward text.

              Note  that  these  expandos  are supported in "save-hook", "fcc-
              hook", "fcc-save-hook", and "index-format-hook".

              They are also supported in the configuration variables $attribu-
              tion,  $forward_attribution_intro, $forward_attribution_trailer,
              $forward_format, $indent_string, $message_format, $pager_format,
              and $post_indent_string.



       ispell
              Type: path
              Default: "ispell"

              How to invoke ispell (GNU's spell-checking software).



       keep_flagged
              Type: boolean
              Default: no

              If  set,  read messages marked as flagged will not be moved from
              your spool mailbox to your $mbox mailbox, or as a  result  of  a
              "mbox-hook" command.



       local_date_header
              Type: boolean
              Default: yes

              If  set, convert the date in the Date header of sent emails into
              local (sender's) timezone.



       mail_check
              Type: number
              Default: 5

              This variable configures how often (in seconds) mutt should look
              for new mail. Also see the $timeout variable.



       mail_check_recent
              Type: boolean
              Default: yes

              When set, Mutt will only notify you about new mail that has been
              received since the last  time  you  opened  the  mailbox.   When
              unset,  Mutt will notify you if any new mail exists in the mail-
              box, regardless of whether you have visited it recently.

              When $mark_old is set, Mutt does not  consider  the  mailbox  to
              contain new mail if only old messages exist.



       mail_check_stats
              Type: boolean
              Default: no

              When set, mutt will periodically calculate message statistics of
              a mailbox while polling for new mail.  It will check for unread,
              flagged,  and  total  message counts.  Because this operation is
              more performance intensive, it defaults to unset, and has a sep-
              arate  option,  $mail_check_stats_interval, to control how often
              to update these counts.

              Message statistics can also be explicitly calculated by invoking
              the <check-stats> function.



       mail_check_stats_interval
              Type: number
              Default: 60

              When  $mail_check_stats  is  set,  this  variable configures how
              often (in seconds) mutt will update message counts.



       mailcap_path
              Type: string
              Default: ""

              This variable specifies which files to consult  when  attempting
              to  display  MIME  bodies  not  directly supported by Mutt.  The
              default value is generated during  startup:  see  the  "mailcap"
              section of the manual.



       mailcap_sanitize
              Type: boolean
              Default: yes

              If  set,  mutt  will  restrict  possible characters in mailcap %
              expandos to a well-defined set of safe characters.  This is  the
              safe  setting,  but  we  are not sure it doesn't break some more
              advanced MIME stuff.

              DON'T CHANGE THIS SETTING UNLESS YOU ARE REALLY  SURE  WHAT  YOU
              ARE DOING!



       maildir_header_cache_verify
              Type: boolean
              Default: yes

              Check  for Maildir unaware programs other than mutt having modi-
              fied maildir files when the header cache is in use.  This incurs
              one  stat(2)  per message every time the folder is opened (which
              can be very slow for NFS folders).



       maildir_trash
              Type: boolean
              Default: no

              If set, messages marked  as  deleted  will  be  saved  with  the
              maildir  trashed  flag  instead  of  unlinked.   Note: this only
              applies to maildir-style mailboxes.  Setting  it  will  have  no
              effect on other mailbox types.



       maildir_check_cur
              Type: boolean
              Default: no

              If  set,  mutt  will  poll both the new and cur directories of a
              maildir folder for new messages.  This might be useful if  other
              programs  interacting  with the folder (e.g. dovecot) are moving
              new messages to the  cur  directory.   Note  that  setting  this
              option  may slow down polling for new messages in large folders,
              since mutt has to scan all cur messages.



       mark_macro_prefix
              Type: string
              Default: "'"

              Prefix for macros created using mark-message.  A new macro auto-
              matically  generated  with <mark-message>a will be composed from
              this prefix and the letter a.



       mark_old
              Type: boolean
              Default: yes

              Controls whether or not mutt marks new unread messages as old if
              you  exit a mailbox without reading them.  With this option set,
              the next time you start mutt, the messages will show up with  an
              "O"  next  to  them  in the index menu, indicating that they are
              old.



       markers
              Type: boolean
              Default: yes

              Controls the display of wrapped lines in the internal pager.  If
              set,  a  "+"  marker  is  displayed  at the beginning of wrapped
              lines.

              Also see the $smart_wrap variable.



       mask
              Type: regular expression
              Default: "!^\.[^.]"

              A regular expression used in the file browser,  optionally  pre-
              ceded  by  the  not  operator "!".  Only files whose names match
              this mask will be shown. The match is always case-sensitive.



       mbox
              Type: path
              Default: "~/mbox"

              This  specifies  the  folder  into  which  read  mail  in   your
              $spoolfile folder will be appended.

              Also see the $move variable.



       mbox_type
              Type: folder magic
              Default: mbox

              The  default mailbox type used when creating new folders. May be
              any of "mbox", "MMDF", "MH" and "Maildir". This is overridden by
              the -m command-line option.



       menu_context
              Type: number
              Default: 0

              This  variable  controls the number of lines of context that are
              given when scrolling through menus. (Similar to $pager_context.)



       menu_move_off
              Type: boolean
              Default: yes

              When unset, the bottom entry of menus will never scroll up  past
              the  bottom  of  the  screen, unless there are less entries than
              lines.  When set, the bottom entry may move off the bottom.



       menu_scroll
              Type: boolean
              Default: no

              When set, menus will be scrolled up or down one  line  when  you
              attempt  to move across a screen boundary.  If unset, the screen
              is cleared and the next or previous page of  the  menu  is  dis-
              played (useful for slow links to avoid many redraws).



       message_cache_clean
              Type: boolean
              Default: no

              If  set,  mutt  will clean out obsolete entries from the message
              cache when the mailbox is synchronized. You probably  only  want
              to  set  it every once in a while, since it can be a little slow
              (especially for large folders).



       message_cachedir
              Type: path
              Default: ""

              Set this to a directory and mutt will cache copies  of  messages
              from  your  IMAP  and  POP  servers here. You are free to remove
              entries at any time.

              When setting this variable to a directory, mutt needs  to  fetch
              every  remote  message only once and can perform regular expres-
              sion searches as fast as for local folders.

              Also see the $message_cache_clean variable.



       message_format
              Type: string
              Default: "%s"

              This is the  string  displayed  in  the  "attachment"  menu  for
              attachments  of  type  message/rfc822.   For  a  full listing of
              defined printf(3)-like sequences see the section on  $index_for-
              mat.



       message_id_format
              Type: string
              Default: "<%z@%f>"

              This  variable  describes the format of the Message-ID generated
              when sending messages.  Mutt 2.0 introduced a more compact  for-
              mat,  but  this  variable  allows the ability to choose your own
              format.  The value may end in "|" to invoke an external  filter.
              See formatstrings-filters.

              Please  note  that the Message-ID value follows a strict syntax,
              and you are responsible for ensuring correctness if  you  change
              this from the default.  In particular, the value must follow the
              syntax in RFC 5322: ""<" id-left "@" id-right ">"".   No  spaces
              are  allowed, and id-left should follow the dot-atom-text syntax
              in the RFC.  The id-right should generally be left at %f.

              The old Message-ID format  can  be  used  by  setting  this  to:
              "<%Y%02m%02d%02H%02M%02S.G%c%p@%f>"

              The following printf(3)-style sequences are understood:
              %c     step counter looping from "A" to "Z"
              %d     current day of the month (GMT)
              %f     $hostname
              %H     current hour using a 24-hour clock (GMT)
              %m     current month number (GMT)
              %M     current minute of the hour (GMT)
              %p     pid of the running mutt process
              %r     3 bytes of pseudorandom data encoded in Base64
              %S     current second of the minute (GMT)
              %x     1 byte of pseudorandom data hex encoded (example: '1b')
              %Y     current year using 4 digits (GMT)
              %z     4  byte  timestamp + 8 bytes of pseudorandom data encoded
                     in Base64


       meta_key
              Type: boolean
              Default: no

              If set, forces Mutt to interpret keystrokes with  the  high  bit
              (bit  8) set as if the user had pressed the Esc key and whatever
              key remains after having the high bit removed.  For example,  if
              the key pressed has an ASCII value of 0xf8, then this is treated
              as if the user had pressed Esc then "x".  This  is  because  the
              result  of removing the high bit from 0xf8 is 0x78, which is the
              ASCII character "x".



       metoo
              Type: boolean
              Default: no

              If unset, Mutt will remove your address  (see  the  "alternates"
              command) from the list of recipients when replying to a message.



       mh_purge
              Type: boolean
              Default: no

              When  unset,  mutt  will  mimic mh's behavior and rename deleted
              messages to ,<old file name> in mh  folders  instead  of  really
              deleting  them.  This  leaves the message on disk but makes pro-
              grams reading the folder ignore it. If the variable is set,  the
              message files will simply be deleted.

              This option is similar to $maildir_trash for Maildir folders.



       mh_seq_flagged
              Type: string
              Default: "flagged"

              The name of the MH sequence used for flagged messages.



       mh_seq_replied
              Type: string
              Default: "replied"

              The name of the MH sequence used to tag replied messages.



       mh_seq_unseen
              Type: string
              Default: "unseen"

              The name of the MH sequence used for unseen messages.



       mime_forward
              Type: quadoption
              Default: no

              When  set,  the message you are forwarding will be attached as a
              separate message/rfc822 MIME part instead  of  included  in  the
              main  body  of  the message.  This is useful for forwarding MIME
              messages so the receiver can properly view the message as it was
              delivered  to  you.  If  you like to switch between MIME and not
              MIME from mail  to  mail,  set  this  variable  to  "ask-no"  or
              "ask-yes".

              Also see $forward_decode and $mime_forward_decode.



       mime_forward_decode
              Type: boolean
              Default: no

              Controls  the  decoding of complex MIME messages into text/plain
              when forwarding a message while $mime_forward is set.  Otherwise
              $forward_decode is used instead.



       mime_forward_rest
              Type: quadoption
              Default: yes

              When  forwarding multiple attachments of a MIME message from the
              attachment menu, attachments which cannot be decoded in  a  rea-
              sonable manner will be attached to the newly composed message if
              this option is set.



       mime_type_query_command
              Type: string
              Default: ""

              This specifies a command to run, to determine the mime type of a
              new    attachment    when    composing    a   message.    Unless
              $mime_type_query_first is set, this will  only  be  run  if  the
              attachment's extension is not found in the mime.types file.

              The  string  may  contain a "%s", which will be substituted with
              the attachment filename.  Mutt will add quotes around the string
              substituted  for  "%s"  automatically according to shell quoting
              rules, so you should avoid adding your own.  If no "%s" is found
              in  the  string, Mutt will append the attachment filename to the
              end of the string.

              The command should output a single line containing  the  attach-
              ment's mime type.

              Suggested values are "xdg-mime query filetype" or "file -bi".



       mime_type_query_first
              Type: boolean
              Default: no

              When  set,  the  $mime_type_query_command will be run before the
              mime.types lookup.



       mix_entry_format
              Type: string
              Default: "%4n %c %-16s %a"

              This variable describes the format of a  remailer  line  on  the
              mixmaster  chain selection screen.  The following printf(3)-like
              sequences are supported:
              %n     The running number on the menu.
              %c     Remailer capabilities.
              %s     The remailer's short name.
              %a     The remailer's e-mail address.


       mixmaster
              Type: path
              Default: "mixmaster"

              This variable contains the path to the Mixmaster binary on  your
              system.   It  is  used with various sets of parameters to gather
              the list of known remailers,  and  to  finally  send  a  message
              through the mixmaster chain.



       move
              Type: quadoption
              Default: no

              Controls  whether  or not Mutt will move read messages from your
              spool mailbox to your $mbox mailbox, or as a result of a  "mbox-
              hook" command.



       muttlisp_inline_eval
              Type: boolean
              Default: no

              If  set,  Mutt  will evaluate bare parenthesis arguments to com-
              mands as MuttLisp expressions.



       narrow_tree
              Type: boolean
              Default: no

              This variable, when set, makes the thread tree narrower,  allow-
              ing deeper threads to fit on the screen.



       net_inc
              Type: number
              Default: 10

              Operations  that  expect to transfer a large amount of data over
              the network will update their progress every $net_inc kilobytes.
              If set to 0, no progress messages will be displayed.

              See also $read_inc, $write_inc and $net_inc.



       new_mail_command
              Type: path
              Default: ""

              If  set,  Mutt  will  call  this  command after a new message is
              received.  See the $status_format documentation for  the  values
              that can be formatted into this command.



       pager
              Type: path
              Default: "builtin"

              This  variable  specifies  which  pager you would like to use to
              view messages. The value "builtin" means  to  use  the  built-in
              pager,  otherwise  this  variable should specify the pathname of
              the external pager you would like to use.

              Using an external pager may have some disadvantages:  Additional
              keystrokes  are  necessary because you can't call mutt functions
              directly from the pager, and screen resizes cause  lines  longer
              than the screen width to be badly formatted in the help menu.

              When  using  an  external  pager,  also  see $prompt_after which
              defaults set.



       pager_context
              Type: number
              Default: 0

              This variable controls the number of lines of context  that  are
              given  when displaying the next or previous page in the internal
              pager.  By default, Mutt will display the line  after  the  last
              one  on  the screen at the top of the next page (0 lines of con-
              text).

              This variable also specifies the amount  of  context  given  for
              search  results.  If  positive,  this  many  lines will be given
              before a match, if 0, the match will be top-aligned.



       pager_format
              Type: string
              Default: "-%Z- %C/%m: %-20.20n   %s%*  -- (%P)"

              This variable controls the format of the one-line message  "sta-
              tus"  displayed before each message in either the internal or an
              external  pager.   The  valid  sequences  are  listed   in   the
              $index_format section.



       pager_index_lines
              Type: number
              Default: 0

              Determines  the  number  of lines of a mini-index which is shown
              when in the pager.  The current message, unless near the top  or
              bottom  of the folder, will be roughly one third of the way down
              this mini-index, giving the reader the context of a few messages
              before  and  after the message.  This is useful, for example, to
              determine how many messages remain to be  read  in  the  current
              thread.   One  of  the lines is reserved for the status bar from
              the index, so a setting of 6 will  only  show  5  lines  of  the
              actual index.  A value of 0 results in no index being shown.  If
              the number of messages  in  the  current  folder  is  less  than
              $pager_index_lines,  then  the index will only use as many lines
              as it needs.



       pager_stop
              Type: boolean
              Default: no

              When set, the internal-pager will not move to the  next  message
              when  you are at the end of a message and invoke the <next-page>
              function.



       pattern_format
              Type: string
              Default: "%2n %-15e  %d"

              This variable describes the format of the  "pattern  completion"
              menu. The following printf(3)-style sequences are understood:
              %d     pattern description
              %e     pattern expression
              %n     index number

       pgp_auto_decode
              Type: boolean
              Default: no

              If  set,  mutt will automatically attempt to decrypt traditional
              PGP messages whenever the user performs an operation which ordi-
              narily  would  result in the contents of the message being oper-
              ated on.  For example, if the user  displays  a  pgp-traditional
              message which has not been manually checked with the <check-tra-
              ditional-pgp> function, mutt will automatically check  the  mes-
              sage for traditional pgp.



       pgp_autoinline
              Type: boolean
              Default: no

              This  option  controls  whether  Mutt generates old-style inline
              (traditional) PGP encrypted or  signed  messages  under  certain
              circumstances.   This  can be overridden by use of the pgp menu,
              when inline is not required.  The GPGME backend does not support
              this option.

              Note  that  Mutt  might  automatically use PGP/MIME for messages
              which consist of more than a single MIME part.  Mutt can be con-
              figured  to  ask  before  sending  PGP/MIME messages when inline
              (traditional) would not work.

              Also see the $pgp_mime_auto variable.

              Also note  that  using  the  old-style  PGP  message  format  is
              strongly deprecated.  (PGP only)



       pgp_check_exit
              Type: boolean
              Default: yes

              If set, mutt will check the exit code of the PGP subprocess when
              signing or encrypting.  A non-zero exit code means that the sub-
              process failed.  (PGP only)



       pgp_check_gpg_decrypt_status_fd
              Type: boolean
              Default: yes

              If  set,  mutt  will  check the status file descriptor output of
              $pgp_decrypt_command and $pgp_decode_command  for  GnuPG  status
              codes indicating successful decryption.  This will check for the
              presence of DECRYPTION_OKAY, absence of  DECRYPTION_FAILED,  and
              that  all  PLAINTEXT  occurs  between  the  BEGIN_DECRYPTION and
              END_DECRYPTION status codes.

              If unset, mutt will instead match the status fd  output  against
              $pgp_decryption_okay.  (PGP only)



       pgp_clearsign_command
              Type: string
              Default: ""

              This  format  is  used  to create an old-style "clearsigned" PGP
              message.  Note that the use of this format  is  strongly  depre-
              cated.

              This is a format string, see the $pgp_decode_command command for
              possible printf(3)-like sequences.  (PGP only)



       pgp_decode_command
              Type: string
              Default: ""

              This format strings specifies a command which is used to  decode
              application/pgp attachments.

              The  PGP  command  formats  have their own set of printf(3)-like
              sequences:
              %p     Expands to PGPPASSFD=0 when a pass phrase is  needed,  to
                     an  empty string otherwise. Note: This may be used with a
                     %? construct.
              %f     Expands to the name of a file containing a message.
              %s     Expands to the name of a file  containing  the  signature
                     part
                                of  a multipart/signed attachment when verify-
                     ing it.
              %a     The value of $pgp_sign_as if set, otherwise the value  of
                     $pgp_default_key.
              %r     One or more key IDs (or fingerprints if available).

              For  examples  on how to configure these formats for the various
              versions of PGP which are floating around, see the pgp  and  gpg
              sample  configuration  files  in the samples/ subdirectory which
              has been installed on your system alongside  the  documentation.
              (PGP only)



       pgp_decrypt_command
              Type: string
              Default: ""

              This command is used to decrypt a PGP encrypted message.

              This is a format string, see the $pgp_decode_command command for
              possible printf(3)-like sequences.  (PGP only)



       pgp_decryption_okay
              Type: regular expression
              Default: ""

              If you assign text to this variable, then an encrypted PGP  mes-
              sage  is  only  considered  successfully decrypted if the output
              from $pgp_decrypt_command contains the text.  This  is  used  to
              protect   against  a  spoofed  encrypted  message,  with  multi-
              part/encrypted headers but containing a block that is not  actu-
              ally encrypted.  (e.g. simply signed and ascii armored text).

              Note that if $pgp_check_gpg_decrypt_status_fd is set, this vari-
              able is ignored.  (PGP only)



       pgp_default_key
              Type: string
              Default: ""

              This is the default key-pair to use for PGP operations.  It will
              be    used    for    encryption   (see   $postpone_encrypt   and
              $pgp_self_encrypt).

              It will also be used for signing unless $pgp_sign_as is set.

              The (now deprecated) pgp_self_encrypt_as is an  alias  for  this
              variable, and should no longer be used.  (PGP only)



       pgp_encrypt_only_command
              Type: string
              Default: ""

              This command is used to encrypt a body part without signing it.

              This is a format string, see the $pgp_decode_command command for
              possible printf(3)-like sequences.  (PGP only)



       pgp_encrypt_sign_command
              Type: string
              Default: ""

              This command is used to both sign and encrypt a body part.

              This is a format string, see the $pgp_decode_command command for
              possible printf(3)-like sequences.  (PGP only)



       pgp_entry_format
              Type: string
              Default: "%4n %t%f %4l/0x%k %-4a %2c %u"

              This variable allows you to customize the PGP key selection menu
              to your personal taste. This string is similar to $index_format,
              but has its own set of printf(3)-like sequences:
              %n     number
              %k     key id
              %u     user id
              %a     algorithm
              %l     key length
              %f     flags
              %c     capabilities
              %t     trust/validity of the key-uid association
              %[<s>] date of the key where <s> is an strftime(3) expression

              (PGP only)



       pgp_export_command
              Type: string
              Default: ""

              This  command is used to export a public key from the user's key
              ring.

              This is a format string, see the $pgp_decode_command command for
              possible printf(3)-like sequences.  (PGP only)



       pgp_getkeys_command
              Type: string
              Default: ""

              This  command is invoked whenever Mutt needs to fetch the public
              key associated with an email address.   Of  the  sequences  sup-
              ported  by  $pgp_decode_command,  %r  is the only printf(3)-like
              sequence used with this format.  Note  that  in  this  case,  %r
              expands  to the email address, not the public key ID (the key ID
              is unknown, which is why Mutt is invoking this  command).   (PGP
              only)



       pgp_good_sign
              Type: regular expression
              Default: ""

              If  you  assign a text to this variable, then a PGP signature is
              only considered verified if the output from  $pgp_verify_command
              contains  the  text. Use this variable if the exit code from the
              command is 0 even for bad signatures.  (PGP only)



       pgp_ignore_subkeys
              Type: boolean
              Default: yes

              Setting this variable will cause Mutt to ignore OpenPGP subkeys.
              Instead,  the  principal key will inherit the subkeys' capabili-
              ties.  Unset this if you want to play interesting key  selection
              games.  (PGP only)



       pgp_import_command
              Type: string
              Default: ""

              This  command  is  used  to import a key from a message into the
              user's public key ring.

              This is a format string, see the $pgp_decode_command command for
              possible printf(3)-like sequences.  (PGP only)



       pgp_list_pubring_command
              Type: string
              Default: ""

              This  command  is  used  to list the public key ring's contents.
              The output format must be analogous to the one used by


              gpg --list-keys --with-colons --with-fingerprint


              This format is also generated by the mutt_pgpring utility  which
              comes with mutt.

              Note:  gpg's fixed-list-mode option should not be used.  It pro-
              duces a different date format which may result in  mutt  showing
              incorrect key generation dates.

              This is a format string, see the $pgp_decode_command command for
              possible printf(3)-like sequences.  Note that in this  case,  %r
              expands  to  the  search  string, which is a list of one or more
              quoted values such as email address, name, or keyid.  (PGP only)



       pgp_list_secring_command
              Type: string
              Default: ""

              This command is used to list the  secret  key  ring's  contents.
              The output format must be analogous to the one used by:


              gpg --list-keys --with-colons --with-fingerprint


              This  format is also generated by the mutt_pgpring utility which
              comes with mutt.

              Note: gpg's fixed-list-mode option should not be used.  It  pro-
              duces  a  different date format which may result in mutt showing
              incorrect key generation dates.

              This is a format string, see the $pgp_decode_command command for
              possible  printf(3)-like  sequences.  Note that in this case, %r
              expands to the search string, which is a list  of  one  or  more
              quoted values such as email address, name, or keyid.  (PGP only)



       pgp_long_ids
              Type: boolean
              Default: yes

              If  set,  use 64 bit PGP key IDs, if unset use the normal 32 bit
              key IDs.  NOTE: Internally, Mutt has transitioned to using  fin-
              gerprints (or long key IDs as a fallback).  This option now only
              controls the display of key IDs in the key selection menu and  a
              few other places.  (PGP only)



       pgp_mime_auto
              Type: quadoption
              Default: ask-yes

              This  option controls whether Mutt will prompt you for automati-
              cally sending a (signed/encrypted) message using  PGP/MIME  when
              inline (traditional) fails (for any reason).

              Also  note  that  using  the  old-style  PGP  message  format is
              strongly deprecated.  (PGP only)



       pgp_replyinline
              Type: boolean
              Default: no

              Setting this variable will cause Mutt to always attempt to  cre-
              ate  an  inline (traditional) message when replying to a message
              which is PGP encrypted/signed inline.  This can be overridden by
              use  of  the pgp menu, when inline is not required.  This option
              does not automatically detect if  the  (replied-to)  message  is
              inline;  instead  it  relies  on  Mutt  internals for previously
              checked/flagged messages.

              Note that Mutt might automatically  use  PGP/MIME  for  messages
              which consist of more than a single MIME part.  Mutt can be con-
              figured to ask before  sending  PGP/MIME  messages  when  inline
              (traditional) would not work.

              Also see the $pgp_mime_auto variable.

              Also  note  that  using  the  old-style  PGP  message  format is
              strongly deprecated.  (PGP only)



       pgp_retainable_sigs
              Type: boolean
              Default: no

              If set, signed and encrypted messages  will  consist  of  nested
              multipart/signed and multipart/encrypted body parts.

              This  is useful for applications like encrypted and signed mail-
              ing lists, where the outer layer  (multipart/encrypted)  can  be
              easily   removed,  while  the  inner  multipart/signed  part  is
              retained.  (PGP only)



       pgp_self_encrypt
              Type: boolean
              Default: yes

              When set, PGP encrypted messages will also  be  encrypted  using
              the key in $pgp_default_key.  (PGP only)



       pgp_show_unusable
              Type: boolean
              Default: yes

              If  set, mutt will display non-usable keys on the PGP key selec-
              tion menu.  This includes keys which  have  been  revoked,  have
              expired,  or  have  been marked as "disabled" by the user.  (PGP
              only)



       pgp_sign_as
              Type: string
              Default: ""

              If you have a different key pair to use for signing, you  should
              set  this to the signing key.  Most people will only need to set
              $pgp_default_key.  It is recommended that you use the keyid form
              to specify your key (e.g. 0x00112233).  (PGP only)



       pgp_sign_command
              Type: string
              Default: ""

              This  command is used to create the detached PGP signature for a
              multipart/signed PGP/MIME body part.

              This is a format string, see the $pgp_decode_command command for
              possible printf(3)-like sequences.  (PGP only)



       pgp_sort_keys
              Type: sort order
              Default: address

              Specifies  how  the entries in the pgp menu are sorted. The fol-
              lowing are legal values:
              address
                     sort alphabetically by user id
              keyid  sort alphabetically by key id
              date   sort by key creation date
              trust  sort by the trust of the key

              If you prefer reverse order of the above values, prefix it  with
              "reverse-".  (PGP only)



       pgp_strict_enc
              Type: boolean
              Default: yes

              If  set, Mutt will automatically encode PGP/MIME signed messages
              as quoted-printable.  Please note that unsetting  this  variable
              may lead to problems with non-verifyable PGP signatures, so only
              change this if you know what you are doing.  (PGP only)



       pgp_timeout
              Type: number (long)
              Default: 300

              The number of seconds  after  which  a  cached  passphrase  will
              expire if not used.  (PGP only)



       pgp_use_gpg_agent
              Type: boolean
              Default: yes

              If  set, mutt expects a gpg-agent(1) process will handle private
              key passphrase prompts.  If unset,  mutt  will  prompt  for  the
              passphrase and pass it via stdin to the pgp command.

              Note that as of version 2.1, GnuPG automatically spawns an agent
              and requires the agent be used for passphrase management.  Since
              that  version  is  increasingly  prevalent,  this  variable  now
              defaults set.

              Mutt works with a GUI or curses pinentry program.  A TTY  pinen-
              try should not be used.

              If you are using an older version of GnuPG without an agent run-
              ning, or another encryption program without an agent,  you  will
              need to unset this variable.  (PGP only)



       pgp_verify_command
              Type: string
              Default: ""

              This command is used to verify PGP signatures.

              This is a format string, see the $pgp_decode_command command for
              possible printf(3)-like sequences.  (PGP only)



       pgp_verify_key_command
              Type: string
              Default: ""

              This command is used to verify  key  information  from  the  key
              selection menu.

              This is a format string, see the $pgp_decode_command command for
              possible printf(3)-like sequences.  (PGP only)



       pipe_decode
              Type: boolean
              Default: no

              Used in  connection  with  the  <pipe-message>  function.   When
              unset,  Mutt  will  pipe the messages without any preprocessing.
              When set, Mutt will attempt to decode the messages first.

              Also see $pipe_decode_weed, which controls whether headers  will
              be weeded when this is set.



       pipe_decode_weed
              Type: boolean
              Default: yes

              For  <pipe-message>, when $pipe_decode is set, this further con-
              trols whether Mutt will weed headers.



       pipe_sep
              Type: string
              Default: "\n"

              The separator to add between messages  when  piping  a  list  of
              tagged messages to an external Unix command.



       pipe_split
              Type: boolean
              Default: no

              Used  in  connection  with the <pipe-message> function following
              <tag-prefix>.  If this variable is unset, when piping a list  of
              tagged messages Mutt will concatenate the messages and will pipe
              them all concatenated.  When set, Mutt will  pipe  the  messages
              one by one.  In both cases the messages are piped in the current
              sorted order, and the $pipe_sep separator is  added  after  each
              message.



       pop_auth_try_all
              Type: boolean
              Default: yes

              If  set,  Mutt  will  try  all available authentication methods.
              When unset, Mutt will only fall  back  to  other  authentication
              methods  if the previous methods are unavailable. If a method is
              available but authentication fails, Mutt will not connect to the
              POP server.



       pop_authenticators
              Type: string
              Default: ""

              This  is  a  colon-delimited list of authentication methods mutt
              may attempt to use to log in to an POP server, in the order mutt
              should  try  them.   Authentication  methods  are either "user",
              "apop" or any SASL mechanism,  e.g.  "digest-md5",  "gssapi"  or
              "cram-md5".   This option is case-insensitive. If this option is
              unset (the default) mutt will  try  all  available  methods,  in
              order from most-secure to least-secure.

              Example:


              set pop_authenticators="digest-md5:apop:user"




       pop_checkinterval
              Type: number
              Default: 60

              This variable configures how often (in seconds) mutt should look
              for new mail in the currently selected mailbox if it  is  a  POP
              mailbox.



       pop_delete
              Type: quadoption
              Default: ask-no

              If  set,  Mutt will delete successfully downloaded messages from
              the POP server  when  using  the  <fetch-mail>  function.   When
              unset,  Mutt  will  download messages but also leave them on the
              POP server.



       pop_host
              Type: string
              Default: ""

              The name of your POP server for the <fetch-mail> function.   You
              can  also  specify  an  alternative port, username and password,
              i.e.:


              [pop[s]://][username[:password]@]popserver[:port]


              where "[...]" denotes an optional part.



       pop_last
              Type: boolean
              Default: no

              If this variable is set, mutt will try to  use  the  "LAST"  POP
              command  for retrieving only unread messages from the POP server
              when using the <fetch-mail> function.



       pop_oauth_refresh_command
              Type: string
              Default: ""

              The command to run to generate an OAUTH refresh token for autho-
              rizing your connection to your POP server.  This command will be
              run on  every  connection  attempt  that  uses  the  OAUTHBEARER
              authentication mechanism.  See "oauth" for details.



       pop_pass
              Type: string
              Default: ""

              Specifies  the  password  for  your POP account.  If unset, Mutt
              will prompt you for your password when you open a POP mailbox.

              Warning: you should only use this  option  when  you  are  on  a
              fairly  secure machine, because the superuser can read your mut-
              trc even if you are the only one who can read the file.



       pop_reconnect
              Type: quadoption
              Default: ask-yes

              Controls whether or not Mutt will try to reconnect  to  the  POP
              server if the connection is lost.



       pop_user
              Type: string
              Default: ""

              Your login name on the POP server.

              This variable defaults to your user name on the local machine.



       post_indent_string
              Type: string
              Default: ""

              Similar  to  the  $attribution  variable,  Mutt will append this
              string after the inclusion of a message which is  being  replied
              to.   For a full listing of defined printf(3)-like sequences see
              the section on $index_format.



       postpone
              Type: quadoption
              Default: ask-yes

              Controls whether or not messages are  saved  in  the  $postponed
              mailbox when you elect not to send immediately.

              Also see the $recall variable.



       postponed
              Type: path
              Default: "~/postponed"

              Mutt  allows  you  to  indefinitely "postpone sending a message"
              which you are editing.  When you choose to postpone  a  message,
              Mutt saves it in the mailbox specified by this variable.

              Also see the $postpone variable.



       postpone_encrypt
              Type: boolean
              Default: no

              When set, postponed messages that are marked for encryption will
              be self-encrypted.  Mutt will first try  to  encrypt  using  the
              value  specified  in $pgp_default_key or $smime_default_key.  If
              those  are  not  set,  it  will  try   the   deprecated   $post-
              pone_encrypt_as.  (Crypto only)



       postpone_encrypt_as
              Type: string
              Default: ""

              This  is  a deprecated fall-back variable for $postpone_encrypt.
              Please  use  $pgp_default_key  or  $smime_default_key.   (Crypto
              only)



       preconnect
              Type: string
              Default: ""

              If  set,  a shell command to be executed if mutt fails to estab-
              lish a connection to the server. This is useful for  setting  up
              secure  connections,  e.g. with ssh(1). If the command returns a
              nonzero status, mutt gives up opening the server. Example:


              set preconnect="ssh -f -q -L 1234:mailhost.net:143 mailhost.net \
              sleep 20 < /dev/null > /dev/null"


              Mailbox "foo" on "mailhost.net" can now be reached  as  "{local-
              host:1234}foo".

              Note:  For  this  example to work, you must be able to log in to
              the remote machine without having to enter a password.



       print
              Type: quadoption
              Default: ask-no

              Controls whether or not Mutt really prints  messages.   This  is
              set to "ask-no" by default, because some people accidentally hit
              "p" often.



       print_command
              Type: path
              Default: "lpr"

              This specifies the command pipe that should  be  used  to  print
              messages.



       print_decode
              Type: boolean
              Default: yes

              Used  in  connection with the <print-message> function.  If this
              option is set, the message is decoded before it is passed to the
              external command specified by $print_command.  If this option is
              unset, no processing will be applied to the message when  print-
              ing  it.  The latter setting may be useful if you are using some
              advanced printer filter which is able to properly format  e-mail
              messages for printing.

              Also see $print_decode_weed, which controls whether headers will
              be weeded when this is set.



       print_decode_weed
              Type: boolean
              Default: yes

              For <print-message>, when $print_decode  is  set,  this  further
              controls whether Mutt will weed headers.



       print_split
              Type: boolean
              Default: no

              Used  in  connection with the <print-message> function.  If this
              option is set, the command specified by $print_command  is  exe-
              cuted  once  for  each  message which is to be printed.  If this
              option is unset, the command specified by $print_command is exe-
              cuted  only  once, and all the messages are concatenated, with a
              form feed as the message separator.

              Those who use the enscript(1) program's mail-printing mode  will
              most likely want to set this option.



       prompt_after
              Type: boolean
              Default: yes

              If  you use an external $pager, setting this variable will cause
              Mutt to prompt you for a command when  the  pager  exits  rather
              than returning to the index menu.  If unset, Mutt will return to
              the index menu when the external pager exits.



       query_command
              Type: path
              Default: ""

              This specifies the  command  Mutt  will  use  to  make  external
              address  queries.   The string may contain a "%s", which will be
              substituted with the query string the user types.  Mutt will add
              quotes  around  the  string  substituted  for "%s" automatically
              according to shell quoting rules, so  you  should  avoid  adding
              your  own.   If no "%s" is found in the string, Mutt will append
              the user's query to the end of the string.  See "query" for more
              information.



       query_format
              Type: string
              Default: "%4c %t %-25.25a %-25.25n %?e?(%e)?"

              This variable describes the format of the "query" menu. The fol-
              lowing printf(3)-style sequences are understood:
              %a     destination address
              %c     current entry number
              %e     extra information *
              %n     destination name
              %t     "*" if current entry is tagged, a space otherwise
              %>X    right justify the rest of the string and pad with "X"
              %|X    pad to the end of the line with "X"
              %*X    soft-fill with character "X" as pad

              For an explanation of "soft-fill", see the  $index_format  docu-
              mentation.

              * = can be optionally printed if nonzero, see the $status_format
              documentation.



       quit
              Type: quadoption
              Default: yes

              This variable controls whether "quit" and "exit"  actually  quit
              from mutt.  If this option is set, they do quit, if it is unset,
              they have no effect, and if it is set to ask-yes or ask-no,  you
              are prompted for confirmation when you try to quit.



       quote_regexp
              Type: regular expression
              Default: "^([ \t]*[|>:}#])+"

              A  regular  expression  used  in the internal pager to determine
              quoted sections of text in the body of a  message.  Quoted  text
              may  be  filtered out using the <toggle-quoted> command, or col-
              ored according to the "color quoted" family of directives.

              Higher levels of quoting  may  be  colored  differently  ("color
              quoted1",  "color  quoted2",  etc.). The quoting level is deter-
              mined by removing the last character from the matched  text  and
              recursively  reapplying the regular expression until it fails to
              produce a match.

              Match detection  may  be  overridden  by  the  $smileys  regular
              expression.



       read_inc
              Type: number
              Default: 10

              If  set  to a value greater than 0, Mutt will display which mes-
              sage it is currently on when reading a mailbox or when  perform-
              ing  search  actions  such  as  search and limit. The message is
              printed after this many messages  have  been  read  or  searched
              (e.g.,  if  set  to  25, Mutt will print a message when it is at
              message 25, and then again when it gets to  message  50).   This
              variable is meant to indicate progress when reading or searching
              large mailboxes which may take some time.  When set to 0, only a
              single message will appear before the reading the mailbox.

              Also  see  the  $write_inc, $net_inc and $time_inc variables and
              the "tuning" section of the manual  for  performance  considera-
              tions.



       read_only
              Type: boolean
              Default: no

              If set, all folders are opened in read-only mode.



       realname
              Type: string
              Default: ""

              This variable specifies what "real" or "personal" name should be
              used when sending messages.

              By default, this is the GECOS field from /etc/passwd.  Note that
              this variable will not be used when the user has set a real name
              in the $from variable.



       recall
              Type: quadoption
              Default: ask-yes

              Controls whether or not Mutt  recalls  postponed  messages  when
              composing a new message.

              Setting  this  variable to yes is not generally useful, and thus
              not recommended.  Note that the <recall-message> function can be
              used to manually recall postponed messages.

              Also see $postponed variable.



       record
              Type: path
              Default: "~/sent"

              This specifies the file into which your outgoing messages should
              be appended.  (This is meant as the primary method for saving  a
              copy  of  your messages, but another way to do this is using the
              "my_hdr" command to  create  a  "Bcc:"  field  with  your  email
              address in it.)

              The  value  of  $record  is  overridden  by  the $force_name and
              $save_name variables, and  the  "fcc-hook"  command.   Also  see
              $copy and $write_bcc.

              Multiple  mailboxes may be specified if $fcc_delimiter is set to
              a string delimiter.



       reflow_space_quotes
              Type: boolean
              Default: yes

              This option controls how quotes from format=flowed messages  are
              displayed  in  the  pager  and  when replying (with $text_flowed
              unset).  When set, this option adds spaces after each  level  of
              quote marks, turning ">>>foo" into "> > > foo".

              Note:  If  $reflow_text  is  unset,  this  option has no effect.
              Also, this option does not affect replies when  $text_flowed  is
              set.



       reflow_text
              Type: boolean
              Default: yes

              When  set,  Mutt  will  reformat  paragraphs in text/plain parts
              marked format=flowed.  If unset, Mutt  will  display  paragraphs
              unaltered from how they appear in the message body.  See RFC3676
              for details on the format=flowed format.

              Also see $reflow_wrap, and $wrap.



       reflow_wrap
              Type: number
              Default: 78

              This variable controls the maximum paragraph width  when  refor-
              matting  text/plain  parts  when  $reflow_text is set.  When the
              value is 0, paragraphs will be wrapped at the  terminal's  right
              margin.   A  positive value sets the paragraph width relative to
              the left margin.  A negative value set the paragraph width rela-
              tive to the right margin.

              Also see $wrap.



       reply_regexp
              Type: regular expression
              Default: "^(re([\[0-9\]+])*|aw):[ \t]*"

              A  regular  expression  used  to  recognize  reply messages when
              threading and replying. The default  value  corresponds  to  the
              English "Re:" and the German "Aw:".



       reply_self
              Type: boolean
              Default: no

              If  unset  and  you  are replying to a message sent by you, Mutt
              will assume that you want to reply to  the  recipients  of  that
              message rather than to yourself.

              Also see the "alternates" command.



       reply_to
              Type: quadoption
              Default: ask-yes

              If  set,  when  replying to a message, Mutt will use the address
              listed in the Reply-to: header as the recipient  of  the  reply.
              If  unset,  it  will  use  the address in the From: header field
              instead.  This option is useful for reading a mailing list  that
              sets the Reply-To: header field to the list address and you want
              to send a private message to the author of a message.



       resolve
              Type: boolean
              Default: yes

              When set, the cursor will be automatically advanced to the  next
              (possibly  undeleted)  message  whenever a command that modifies
              the current message is executed.



       resume_draft_files
              Type: boolean
              Default: no

              If set, draft files (specified by -H on the  command  line)  are
              processed  similarly  to  when  resuming  a  postponed  message.
              Recipients are not prompted for; send-hooks are  not  evaluated;
              no  alias expansion takes place; user-defined headers and signa-
              tures are not added to the message.



       resume_edited_draft_files
              Type: boolean
              Default: yes

              If set, draft files previously edited (via -E -H on the  command
              line)  will have $resume_draft_files automatically set when they
              are used as a draft file again.

              The first time a draft file is saved, mutt will  add  a  header,
              X-Mutt-Resume-Draft  to the saved file.  The next time the draft
              file  is  read  in,  if  mutt  sees  the  header,  it  will  set
              $resume_draft_files.

              This   option   is  designed  to  prevent  multiple  signatures,
              user-defined headers, and other processing  effects  from  being
              made multiple times to the draft file.



       reverse_alias
              Type: boolean
              Default: no

              This  variable  controls  whether  or  not Mutt will display the
              "personal" name from your aliases in the index menu if it  finds
              an alias that matches the message's sender.  For example, if you
              have the following alias:


              alias juser abd30425@somewhere.net (Joe User)


              and then you receive mail which contains the following header:


              From: abd30425@somewhere.net


              It would be displayed in the index menu as "Joe User" instead of
              "abd30425@somewhere.net."   This  is  useful  when  the person's
              e-mail address is not human friendly.



       reverse_name
              Type: boolean
              Default: no

              It may sometimes arrive that  you  receive  mail  to  a  certain
              machine, move the messages to another machine, and reply to some
              the messages from there.  If this variable is set,  the  default
              From:  line  of  the  reply  messages is built using the address
              where you received the messages you  are  replying  to  if  that
              address matches your "alternates".  If the variable is unset, or
              the address that would be used doesn't match your  "alternates",
              the From: line will use your address on the current machine.

              Also see the "alternates" command and $reverse_realname.



       reverse_realname
              Type: boolean
              Default: yes

              This  variable fine-tunes the behavior of the $reverse_name fea-
              ture.

              When it is unset, Mutt will remove  the  real  name  part  of  a
              matching  address.   This  allows  the  use of the email address
              without having to also use what the sender put in the real  name
              field.

              When it is set, Mutt will use the matching address as-is.

              In either case, a missing real name will be filled in afterwards
              using the value of $realname.



       rfc2047_parameters
              Type: boolean
              Default: no

              When this variable is set, Mutt will decode RFC2047-encoded MIME
              parameters. You want to set this variable when mutt suggests you
              to save attachments to files named like:


              =?iso-8859-1?Q?file=5F=E4=5F991116=2Ezip?=


              When this variable is set interactively,  the  change  won't  be
              active until you change folders.

              Note  that  this use of RFC2047's encoding is explicitly prohib-
              ited by the standard, but nevertheless encountered in the wild.

              Also note that setting this parameter will not have  the  effect
              that  mutt  generates this kind of encoding.  Instead, mutt will
              unconditionally use the encoding specified in RFC2231.



       save_address
              Type: boolean
              Default: no

              If set, mutt will take the sender's full address when choosing a
              default  folder  for saving a mail. If $save_name or $force_name
              is set too, the selection of the Fcc folder will be  changed  as
              well.



       save_empty
              Type: boolean
              Default: yes

              When  unset,  mailboxes  which contain no saved messages will be
              removed when closed (the exception is $spoolfile which is  never
              removed).  If set, mailboxes are never removed.

              Note:  This only applies to mbox and MMDF folders, Mutt does not
              delete MH and Maildir directories.



       save_history
              Type: number
              Default: 0

              This variable controls the size of the  history  (per  category)
              saved in the $history_file file.



       save_name
              Type: boolean
              Default: no

              This  variable  controls  how  copies  of  outgoing messages are
              saved.  When set, a check is made to see if a mailbox  specified
              by the recipient address exists (this is done by searching for a
              mailbox in the $folder directory with the username part  of  the
              recipient address).  If the mailbox exists, the outgoing message
              will be saved to that mailbox, otherwise the message is saved to
              the $record mailbox.

              Also see the $force_name variable.



       score
              Type: boolean
              Default: yes

              When this variable is unset, scoring is turned off.  This can be
              useful to selectively disable scoring for certain  folders  when
              the $score_threshold_delete variable and related are used.



       score_threshold_delete
              Type: number
              Default: -1

              Messages which have been assigned a score equal to or lower than
              the value of this variable are automatically marked for deletion
              by  mutt.  Since mutt scores are always greater than or equal to
              zero, the default setting of this variable  will  never  mark  a
              message for deletion.



       score_threshold_flag
              Type: number
              Default: 9999

              Messages  which have been assigned a score greater than or equal
              to this variable's value are automatically marked "flagged".



       score_threshold_read
              Type: number
              Default: -1

              Messages which have been assigned a score equal to or lower than
              the  value  of this variable are automatically marked as read by
              mutt.  Since mutt scores are always greater  than  or  equal  to
              zero,  the  default  setting  of this variable will never mark a
              message read.



       search_context
              Type: number
              Default: 0

              For the pager, this variable specifies the number of lines shown
              before  search  results.  By  default,  search  results  will be
              top-aligned.



       send_charset
              Type: string
              Default: "us-ascii:iso-8859-1:utf-8"

              A colon-delimited list of character sets for outgoing  messages.
              Mutt will use the first character set into which the text can be
              converted exactly.  If your $charset  is  not  "iso-8859-1"  and
              recipients  may  not  understand  "UTF-8",  it  is  advisable to
              include in the list an appropriate widely used standard  charac-
              ter set (such as "iso-8859-2", "koi8-r" or "iso-2022-jp") either
              instead of or after "iso-8859-1".

              In case the text cannot be converted into one of these  exactly,
              mutt uses $charset as a fallback.



       send_multipart_alternative
              Type: quadoption
              Default: no

              If set, Mutt will generate a multipart/alternative container and
              an  alternative  part  using  the  filter  script  specified  in
              $send_multipart_alternative_filter.   See the section "MIME Mul-
              tipart/Alternative" (alternative-order).

              Note that enabling multipart/alternative is not compatible  with
              inline PGP encryption.  Mutt will prompt to use PGP/MIME in that
              case.



       send_multipart_alternative_filter
              Type: path
              Default: ""

              This specifies a filter script,  which  will  convert  the  main
              (composed)  message  of the email to an alternative format.  The
              message will be piped to the filter's stdin.  The expected  out-
              put  of  the  filter is the generated mime type, e.g. text/html,
              followed by a blank line, and then the converted  content.   See
              the section "MIME Multipart/Alternative" (alternative-order).



       sendmail
              Type: path
              Default: "/usr/sbin/sendmail -oem -oi"

              Specifies the program and arguments used to deliver mail sent by
              Mutt.  Mutt expects that the specified program interprets  addi-
              tional  arguments  as  recipient  addresses.   Mutt  appends all
              recipients after adding a -- delimiter (if not already present).
              Additional flags, such as for $use_8bitmime, $use_envelope_from,
              $dsn_notify, or $dsn_return will be added before the delimiter.

              See also: $write_bcc.



       sendmail_wait
              Type: number
              Default: 0

              Specifies the number  of  seconds  to  wait  for  the  $sendmail
              process  to  finish before giving up and putting delivery in the
              background.

              Mutt interprets the value of this variable as follows:
              >0     number of seconds to wait for sendmail to  finish  before
                     continuing
              0      wait forever for sendmail to finish
              <0     always put sendmail in the background without waiting

              Note that if you specify a value other than 0, the output of the
              child process will be put in a temporary file.  If there is some
              error, you will be informed as to where to find the output.



       shell
              Type: path
              Default: ""

              Command to use when spawning a subshell.  By default, the user's
              login shell from /etc/passwd is used.



       sidebar_delim_chars
              Type: string
              Default: "/."

              This contains the list of characters which  you  would  like  to
              treat as folder separators for displaying paths in the sidebar.

              Local  mail  is  often arranged in directories: `dir1/dir2/mail-
              box'.


              set sidebar_delim_chars='/'


              IMAP mailboxes are often named: `folder1.folder2.mailbox'.


              set sidebar_delim_chars='.'

              bar_indent_string.



       sidebar_divider_char
              Type: string
              Default: "|"

              This  specifies  the  characters to be drawn between the sidebar
              (when visible) and the other  Mutt  panels.  ASCII  and  Unicode
              line-drawing characters are supported.



       sidebar_folder_indent
              Type: boolean
              Default: no

              Set this to indent mailboxes in the sidebar.

              See  also:  $sidebar_short_path,  $sidebar_indent_string, $side-
              bar_delim_chars.



       sidebar_format
              Type: string
              Default: "%B%*  %n"

              This variable allows you to customize the sidebar display.  This
              string  is  similar  to  $index_format,  but  has its own set of
              printf(3)-like sequences:
              %B     Name of the mailbox
              %S     * Size of mailbox (total number of messages)
              %N     * Number of unread messages in the mailbox
              %n     N if mailbox has new mail, blank otherwise
              %F     * Number of Flagged messages in the mailbox
              %!     "!" : one flagged message; "!!" : two  flagged  messages;
                     "n!"  : n flagged messages (for n > 2).  Otherwise prints
                     nothing.
              %d     * @ Number of deleted messages
              %L     * @ Number of messages after limiting
              %t     * @ Number of tagged messages
              %>X    right justify the rest of the string and pad with "X"
              %|X    pad to the end of the line with "X"
              %*X    soft-fill with character "X" as pad

              * = Can be optionally printed if nonzero @ = Only applicable  to
              the current folder

              In  order  to  use %S, %N, %F, and %!, $mail_check_stats must be
              set.  When thus set,  a  suggested  value  for  this  option  is
              "%B%?F? [%F]?%* %?N?%N/?%S".



       sidebar_indent_string
              Type: string
              Default: "  "

              This  specifies  the  string that is used to indent mailboxes in
              the sidebar.  It defaults to two spaces.

              See also:  $sidebar_short_path,  $sidebar_folder_indent,  $side-
              bar_delim_chars.



       sidebar_new_mail_only
              Type: boolean
              Default: no

              When  set,  the  sidebar  will only display mailboxes containing
              new, or flagged, mail.

              See also: sidebar_whitelist.



       sidebar_next_new_wrap
              Type: boolean
              Default: no

              When set, the <sidebar-next-new> command will not stop  and  the
              end  of the list of mailboxes, but wrap around to the beginning.
              The <sidebar-prev-new> command is similarly  affected,  wrapping
              around to the end of the list.



       sidebar_relative_shortpath_indent
              Type: boolean
              Default: no

              When set, this option changes how $sidebar_short_path and $side-
              bar_folder_indent perform shortening and indentation: both  will
              look at the previous sidebar entries and shorten/indent relative
              to the most recent parent.

              An example of this option set/unset for mailboxes listed in this
              order, with $sidebar_short_path=yes, $sidebar_folder_indent=yes,
              and $sidebar_indent_string="->":
              mailbox
                     set unset
              =a.b   =a.b ->b
              =a.b.c.d
                     ->c.d ->->->d
              =a.b.e ->e ->->e

              The second line illustrates most clearly.  With this option set,
              =a.b.c.d is shortened relative to =a.b, becoming c.d; it is also
              indented one place relative to =a.b.   With  this  option  unset
              =a.b.c.d  is always shortened to the last part of the mailbox, d
              and is indented three places, with respect  to  $folder  (repre-
              sented by '=').

              When  set,  the  third  line will also be indented and shortened
              relative to the first line.



       sidebar_short_path
              Type: boolean
              Default: no

              By default the sidebar will show the mailbox's path, relative to
              the $folder variable. Setting sidebar_shortpath=yes will shorten
              the names relative to the previous name. Here's an example:
              shortpath=no
                     shortpath=yes      shortpath=yes,       folderindent=yes,
                     indentstr=".."
              fruit  fruit fruit
              fruit.apple
                     apple ..apple
              fruit.banana
                     banana ..banana
              fruit.cherry
                     cherry ..cherry

              See  also:  $sidebar_delim_chars, $sidebar_folder_indent, $side-
              bar_indent_string.



       sidebar_sort_method
              Type: sort order
              Default: unsorted

              Specifies how to  sort  mailbox  entries  in  the  sidebar.   By
              default, the entries are sorted alphabetically.  Valid values:
              - alpha (alphabetically)
              - count (all message count)
              - flagged (flagged message count)
              - name (alphabetically)
              - new (unread message count)
              - path (alphabetically)
              - unread (unread message count)
              - unsorted

              You  may optionally use the "reverse-" prefix to specify reverse
              sorting        order        (example:         "set         side-
              bar_sort_method=reverse-alpha").



       sidebar_use_mailbox_shortcuts
              Type: boolean
              Default: no

              When  set,  sidebar  mailboxes  will  be  displayed with mailbox
              shortcut prefixes "=" or "~".

              When unset, the sidebar will trim off a matching $folder  prefix
              but otherwise not use mailbox shortcuts.



       sidebar_visible
              Type: boolean
              Default: no

              This specifies whether or not to show sidebar. The sidebar shows
              a list of all your mailboxes.

              See also: $sidebar_format, $sidebar_width



       sidebar_width
              Type: number
              Default: 30

              This controls the width of  the  sidebar.   It  is  measured  in
              screen  columns.  For example: sidebar_width=20 could display 20
              ASCII characters, or 10 Chinese characters.



       sig_dashes
              Type: boolean
              Default: yes

              If set, a line containing "-- " (note the trailing  space)  will
              be  inserted before your $signature.  It is strongly recommended
              that you not unset this variable unless your signature  contains
              just  your  name.   The reason for this is because many software
              packages use "-- \n" to detect  your  signature.   For  example,
              Mutt  has  the ability to highlight the signature in a different
              color in the built-in pager.



       sig_on_top
              Type: boolean
              Default: no

              If set, the signature will be included before any quoted or for-
              warded  text.   It  is  strongly recommended that you do not set
              this variable unless you really know what you are doing, and are
              prepared to take some heat from netiquette guardians.



       signature
              Type: path
              Default: "~/.signature"

              Specifies  the  filename of your signature, which is appended to
              all outgoing messages.   If the filename ends with a pipe ("|"),
              it  is assumed that filename is a shell command and input should
              be read from its standard output.



       simple_search
              Type: string
              Default: "~f %s | ~s %s"

              Specifies how Mutt should expand a simple  search  into  a  real
              search  pattern.   A  simple search is one that does not contain
              any of the "~"  pattern  modifiers.   See  "patterns"  for  more
              information on search patterns.

              For  example,  if  you  simply  type  "joe" at a search or limit
              prompt, Mutt will automatically expand it to the value specified
              by  this  variable  by  replacing "%s" with the supplied string.
              For the default value, "joe" would be expanded to: "~f joe |  ~s
              joe".



       size_show_bytes
              Type: boolean
              Default: no

              If  set, message sizes will display bytes for values less than 1
              kilobyte.  See formatstrings-size.



       size_show_fractions
              Type: boolean
              Default: yes

              If set, message sizes will be displayed with  a  single  decimal
              value  for  sizes  from 0 to 10 kilobytes and 1 to 10 megabytes.
              See formatstrings-size.



       size_show_mb
              Type: boolean
              Default: yes

              If set, message sizes will display megabytes for values  greater
              than or equal to 1 megabyte.  See formatstrings-size.



       size_units_on_left
              Type: boolean
              Default: no

              If set, message sizes units will be displayed to the left of the
              number.  See formatstrings-size.



       sleep_time
              Type: number
              Default: 1

              Specifies time, in seconds, to pause  while  displaying  certain
              informational  messages,  while moving from folder to folder and
              after expunging messages from the current folder.   The  default
              is  to pause one second, so a value of zero for this option sup-
              presses the pause.



       smart_wrap
              Type: boolean
              Default: yes

              Controls the display of lines longer than the  screen  width  in
              the  internal  pager.  If  set, long lines are wrapped at a word
              boundary.  If unset, lines are  simply  wrapped  at  the  screen
              edge. Also see the $markers variable.



       smileys
              Type: regular expression
              Default: "(>From )|(:[-^]?[][)(><}{|/DP])"

              The  pager  uses  this variable to catch some common false posi-
              tives of $quote_regexp, most notably smileys and not consider  a
              line  quoted  text if it also matches $smileys. This mostly hap-
              pens at the beginning of a line.



       smime_ask_cert_label
              Type: boolean
              Default: yes

              This flag controls whether you want to be asked to enter a label
              for  a  certificate about to be added to the database or not. It
              is set by default.  (S/MIME only)



       smime_ca_location
              Type: path
              Default: ""

              This variable contains the name of either a directory, or a file
              which  contains  trusted  certificates  for  use  with  OpenSSL.
              (S/MIME only)



       smime_certificates
              Type: path
              Default: ""

              Since for S/MIME there is no pubring/secring as with  PGP,  mutt
              has  to  handle storage and retrieval of keys by itself. This is
              very basic right now, and keys and certificates  are  stored  in
              two   different   directories,  both  named  as  the  hash-value
              retrieved from OpenSSL. There is an index  file  which  contains
              mailbox-address  keyid  pairs, and which can be manually edited.
              This option points to the location of the certificates.  (S/MIME
              only)



       smime_decrypt_command
              Type: string
              Default: ""

              This  format string specifies a command which is used to decrypt
              application/x-pkcs7-mime attachments.

              The OpenSSL command formats have their own set of printf(3)-like
              sequences similar to PGP's:
              %f     Expands to the name of a file containing a message.
              %s     Expands  to  the  name of a file containing the signature
                     part
                                of a multipart/signed attachment when  verify-
                     ing it.
              %k     The key-pair specified with $smime_default_key
              %c     One or more certificate IDs.
              %a     The algorithm used for encryption.
              %d     The    message    digest    algorithm    specified   with
                     $smime_sign_digest_alg.
              %C     CA location:  Depending on whether $smime_ca_location
                                points to a directory or file, this expands to
                                "-CApath   $smime_ca_location"   or   "-CAfile
                     $smime_ca_location".

              For examples on how to configure these formats, see the smime.rc
              in the samples/ subdirectory which has been  installed  on  your
              system alongside the documentation.  (S/MIME only)



       smime_decrypt_use_default_key
              Type: boolean
              Default: yes

              If  set  (default)  this  tells  mutt to use the default key for
              decryption.   Otherwise,   if   managing    multiple    certifi-
              cate-key-pairs,  mutt  will  try  to  use the mailbox-address to
              determine the key to use. It will ask you to supply a key, if it
              can't find one.  (S/MIME only)



       smime_default_key
              Type: string
              Default: ""

              This  is  the default key-pair to use for S/MIME operations, and
              must be set to the keyid (the hash-value that OpenSSL generates)
              to work properly.

              It  will  be  used  for  encryption  (see  $postpone_encrypt and
              $smime_self_encrypt). If GPGME is enabled, this is  the  key  id
              displayed by gpgsm.

              It      will      be      used     for     decryption     unless
              $smime_decrypt_use_default_key is unset.

              It will also be used for signing unless $smime_sign_as is set.

              The (now deprecated) smime_self_encrypt_as is an alias for  this
              variable, and should no longer be used.  (S/MIME only)



       smime_encrypt_command
              Type: string
              Default: ""

              This command is used to create encrypted S/MIME messages.

              This  is a format string, see the $smime_decrypt_command command
              for possible printf(3)-like sequences.  (S/MIME only)



       smime_encrypt_with
              Type: string
              Default: "aes256"

              This sets the algorithm that  should  be  used  for  encryption.
              Valid  choices  are "aes128", "aes192", "aes256", "des", "des3",
              "rc2-40", "rc2-64", "rc2-128".  (S/MIME only)



       smime_get_cert_command
              Type: string
              Default: ""

              This command is used to extract X509 certificates from  a  PKCS7
              structure.

              This  is a format string, see the $smime_decrypt_command command
              for possible printf(3)-like sequences.  (S/MIME only)



       smime_get_cert_email_command
              Type: string
              Default: ""

              This command is used to extract the mail  address(es)  used  for
              storing  X509  certificates,  and  for verification purposes (to
              check whether the certificate was issued for the sender's  mail-
              box).

              This  is a format string, see the $smime_decrypt_command command
              for possible printf(3)-like sequences.  (S/MIME only)



       smime_get_signer_cert_command
              Type: string
              Default: ""

              This command is used to extract only the signers  X509  certifi-
              cate  from  a  S/MIME signature, so that the certificate's owner
              may get compared to the email's "From:" field.

              This is a format string, see the $smime_decrypt_command  command
              for possible printf(3)-like sequences.  (S/MIME only)



       smime_import_cert_command
              Type: string
              Default: ""

              This command is used to import a certificate via smime_keys.

              This  is a format string, see the $smime_decrypt_command command
              for possible printf(3)-like sequences.  (S/MIME only)



       smime_is_default
              Type: boolean
              Default: no

              The  default  behavior  of  mutt  is   to   use   PGP   on   all
              auto-sign/encryption  operations. To override and to use OpenSSL
              instead this must be set.  However, this  has  no  effect  while
              replying, since mutt will automatically select the same applica-
              tion that was used to sign/encrypt the original message.   (Note
              that    this   variable   can   be   overridden   by   unsetting
              $crypt_autosmime.)  (S/MIME only)



       smime_keys
              Type: path
              Default: ""

              Since for S/MIME there is no pubring/secring as with  PGP,  mutt
              has  to  handle  storage  and retrieval of keys/certs by itself.
              This is very basic right now, and stores keys  and  certificates
              in  two  different  directories,  both  named  as the hash-value
              retrieved from OpenSSL. There is an index  file  which  contains
              mailbox-address  keyid  pair,  and which can be manually edited.
              This option points to the location of the private keys.  (S/MIME
              only)



       smime_pk7out_command
              Type: string
              Default: ""

              This  command is used to extract PKCS7 structures of S/MIME sig-
              natures, in order to extract the public X509 certificate(s).

              This is a format string, see the $smime_decrypt_command  command
              for possible printf(3)-like sequences.  (S/MIME only)



       smime_self_encrypt
              Type: boolean
              Default: yes

              When set, S/MIME encrypted messages will also be encrypted using
              the certificate in $smime_default_key.  (S/MIME only)



       smime_sign_as
              Type: string
              Default: ""

              If you have a separate key to use for signing,  you  should  set
              this  to  the  signing  key.  Most  people will only need to set
              $smime_default_key.  (S/MIME only)



       smime_sign_command
              Type: string
              Default: ""

              This command is used to created S/MIME signatures of type multi-
              part/signed, which can be read by all mail clients.

              This  is a format string, see the $smime_decrypt_command command
              for possible printf(3)-like sequences.  NOTE:  %c  and  %k  will
              default  to $smime_sign_as if set, otherwise $smime_default_key.
              (S/MIME only)



       smime_sign_digest_alg
              Type: string
              Default: "sha256"

              This sets the algorithm that should be used  for  the  signature
              message  digest.   Valid  choices  are  "md5", "sha1", "sha224",
              "sha256", "sha384", "sha512".  (S/MIME only)



       smime_sign_opaque_command
              Type: string
              Default: ""

              This command is used to created S/MIME signatures of type appli-
              cation/x-pkcs7-signature,  which  can  only  be  handled by mail
              clients supporting the S/MIME extension.

              This is a format string, see the $smime_decrypt_command  command
              for possible printf(3)-like sequences.  (S/MIME only)



       smime_timeout
              Type: number (long)
              Default: 300

              The  number  of  seconds  after  which  a cached passphrase will
              expire if not used.  (S/MIME only)



       smime_verify_command
              Type: string
              Default: ""

              This command is used to verify S/MIME signatures of type  multi-
              part/signed.

              This  is a format string, see the $smime_decrypt_command command
              for possible printf(3)-like sequences.  (S/MIME only)



       smime_verify_opaque_command
              Type: string
              Default: ""

              This command is used to verify S/MIME signatures of type  appli-
              cation/x-pkcs7-mime.

              This  is a format string, see the $smime_decrypt_command command
              for possible printf(3)-like sequences.  (S/MIME only)



       smtp_authenticators
              Type: string
              Default: ""

              This is a colon-delimited list of  authentication  methods  mutt
              may  attempt  to  use  to log in to an SMTP server, in the order
              mutt should try them.  Authentication methods are any SASL mech-
              anism,  e.g.  "digest-md5", "gssapi" or "cram-md5".  This option
              is case-insensitive. If it is "unset" (the  default)  mutt  will
              try   all  available  methods,  in  order  from  most-secure  to
              least-secure.

              Example:


              set smtp_authenticators="digest-md5:cram-md5"




       smtp_oauth_refresh_command
              Type: string
              Default: ""

              The command to run to generate an OAUTH refresh token for autho-
              rizing  your  connection to your SMTP server.  This command will
              be run on every connection attempt  that  uses  the  OAUTHBEARER
              authentication mechanism.  See "oauth" for details.



       smtp_pass
              Type: string
              Default: ""

              Specifies  the  password  for your SMTP account.  If unset, Mutt
              will prompt you for your password when you first send  mail  via
              SMTP.  See $smtp_url to configure mutt to send mail via SMTP.

              Warning:  you  should  only  use  this  option when you are on a
              fairly secure machine, because the superuser can read your  mut-
              trc even if you are the only one who can read the file.



       smtp_url
              Type: string
              Default: ""

              Defines  the  SMTP  smarthost where sent messages should relayed
              for delivery. This should take the form of an SMTP URL, e.g.:


              smtp[s]://[user[:pass]@]host[:port]


              where "[...]" denotes an optional part.  Setting  this  variable
              overrides the value of the $sendmail variable.

              Also see $write_bcc.



       sort
              Type: sort order
              Default: date

              Specifies  how to sort messages in the "index" menu.  Valid val-
              ues are:
              - date or date-sent
              - date-received
              - from
              - mailbox-order (unsorted)
              - score
              - size
              - spam
              - subject
              - threads
              - to

              You may optionally use the "reverse-" prefix to specify  reverse
              sorting order (example: "set sort=reverse-date-sent").



       sort_alias
              Type: sort order
              Default: alias

              Specifies  how  the entries in the "alias" menu are sorted.  The
              following are legal values:
              - address (sort alphabetically by email address)
              - alias (sort alphabetically by alias name)
              - unsorted (leave in order specified in .muttrc)


       sort_aux
              Type: sort order
              Default: date

              This provides a secondary sort for messages in the "index" menu,
              used when the $sort value is equal for two messages.

              When  sorting by threads, this variable controls how threads are
              sorted in relation to other threads, and how the branches of the
              thread  trees  are  sorted.   This  can be set to any value that
              $sort can, except "threads" (in that case, mutt  will  just  use
              "date-sent").   You can also specify the "last-" prefix in addi-
              tion to the "reverse-"  prefix,  but  "last-"  must  come  after
              "reverse-".   The  "last-"  prefix  causes messages to be sorted
              against its siblings by which has the last descendant, using the
              rest of $sort_aux as an ordering.  For instance,


              set sort_aux=last-date-received


              would  mean  that if a new message is received in a thread, that
              thread becomes the last one displayed (or the first, if you have
              "set sort=reverse-threads".)

              Note:  For  reversed-threads  $sort order, $sort_aux is reversed
              again (which is not the right thing to do, but kept to not break
              any existing configuration setting).



       sort_browser
              Type: sort order
              Default: alpha

              Specifies  how to sort entries in the file browser.  By default,
              the entries are sorted alphabetically.  Valid values:
              - alpha (alphabetically)
              - count
              - date
              - size
              - unread
              - unsorted

              You may optionally use the "reverse-" prefix to specify  reverse
              sorting order (example: "set sort_browser=reverse-date").



       sort_browser_mailboxes
              Type: sort order
              Default: unsorted

              Specifies  how  to  sort  entries  in  the  mailbox browser.  By
              default, the entries are unsorted, displayed in the  same  order
              as listed in the "mailboxes" command.  Valid values:
              - alpha (alphabetically)
              - count
              - date
              - size
              - unread
              - unsorted

              You  may optionally use the "reverse-" prefix to specify reverse
              sorting     order     (example:     "set      sort_browser_mail-
              boxes=reverse-alpha").



       sort_re
              Type: boolean
              Default: yes

              This  variable  is  only  useful  when  sorting  by threads with
              $strict_threads unset.  In that case, it changes  the  heuristic
              mutt  uses  to  thread  messages by subject.  With $sort_re set,
              mutt will only attach a message as the child of another  message
              by  subject  if  the  subject of the child message starts with a
              substring matching the setting of $reply_regexp.  With  $sort_re
              unset,  mutt  will attach the message whether or not this is the
              case, as long as the non-$reply_regexp parts  of  both  messages
              are identical.



       spam_separator
              Type: string
              Default: ","

              This  variable  controls what happens when multiple spam headers
              are matched: if unset, each successive header will overwrite any
              previous  matches value for the spam label. If set, each succes-
              sive match will append to the previous,  using  this  variable's
              value as a separator.



       spoolfile
              Type: path
              Default: ""

              If  your spool mailbox is in a non-default place where Mutt can-
              not find it, you can specify its location  with  this  variable.
              Mutt  will initially set this variable to the value of the envi-
              ronment variable $MAIL or $MAILDIR if either is defined.



       ssl_ca_certificates_file
              Type: path
              Default: ""

              This variable specifies a file containing  trusted  CA  certifi-
              cates.   Any server certificate that is signed with one of these
              CA certificates is also automatically accepted. (GnuTLS only)

              Example:


              set ssl_ca_certificates_file=/etc/ssl/certs/ca-certificates.crt




       ssl_client_cert
              Type: path
              Default: ""

              The file containing a client certificate and its associated pri-
              vate key.



       ssl_force_tls
              Type: boolean
              Default: yes

              If  this variable is set, Mutt will require that all connections
              to remote servers be encrypted. Furthermore it will  attempt  to
              negotiate TLS even if the server does not advertise the capabil-
              ity, since it would otherwise have to abort the connection  any-
              way. This option supersedes $ssl_starttls.



       ssl_min_dh_prime_bits
              Type: number
              Default: 0

              This  variable  specifies  the minimum acceptable prime size (in
              bits) for use in any Diffie-Hellman key exchange. A value  of  0
              will use the default from the GNUTLS library. (GnuTLS only)



       ssl_starttls
              Type: quadoption
              Default: yes

              If  set  (the  default),  mutt  will  attempt to use STARTTLS on
              servers advertising the capability. When unset,  mutt  will  not
              attempt to use STARTTLS regardless of the server's capabilities.

              Note  that STARTTLS is subject to many kinds of attacks, includ-
              ing the ability  of  a  machine-in-the-middle  to  suppress  the
              advertising  of  support.  Setting $ssl_force_tls is recommended
              if you rely on STARTTLS.



       ssl_use_sslv2
              Type: boolean
              Default: no

              If set , Mutt will use SSLv2  when  communicating  with  servers
              that  request it. N.B. As of 2011, SSLv2 is considered insecure,
              and         using          is          inadvisable.          See
              https://tools.ietf.org/html/rfc6176 .  (OpenSSL only)



       ssl_use_sslv3
              Type: boolean
              Default: no

              If  set  ,  Mutt  will use SSLv3 when communicating with servers
              that request it. N.B. As of 2015, SSLv3 is considered  insecure,
              and        using        it       is       inadvisable.       See
              https://tools.ietf.org/html/rfc7525 .



       ssl_use_tlsv1
              Type: boolean
              Default: no

              If set , Mutt will use TLSv1.0 when communicating  with  servers
              that  request  it.  N.B. As of 2015, TLSv1.0 is considered inse-
              cure,     and     using     it     is      inadvisable.      See
              https://tools.ietf.org/html/rfc7525 .



       ssl_use_tlsv1_1
              Type: boolean
              Default: no

              If  set  , Mutt will use TLSv1.1 when communicating with servers
              that request it. N.B. As of 2015, TLSv1.1  is  considered  inse-
              cure,      and      using     it     is     inadvisable.     See
              https://tools.ietf.org/html/rfc7525 .



       ssl_use_tlsv1_2
              Type: boolean
              Default: yes

              If set , Mutt will use TLSv1.2 when communicating  with  servers
              that request it.



       ssl_use_tlsv1_3
              Type: boolean
              Default: yes

              If  set  , Mutt will use TLSv1.3 when communicating with servers
              that request it.



       ssl_usesystemcerts
              Type: boolean
              Default: yes

              If set to yes, mutt will use CA certificates in the  system-wide
              certificate  store  when  checking  if  a  server certificate is
              signed by a trusted CA. (OpenSSL only)



       ssl_verify_dates
              Type: boolean
              Default: yes

              If set (the default),  mutt  will  not  automatically  accept  a
              server  certificate  that  is  either  not  yet valid or already
              expired. You should only unset this for particular known  hosts,
              using the <account-hook> function.



       ssl_verify_host
              Type: boolean
              Default: yes

              If  set  (the  default),  mutt  will  not automatically accept a
              server certificate whose host name does not match the host  used
              in  your  folder  URL. You should only unset this for particular
              known hosts, using the <account-hook> function.



       ssl_verify_host_override
              Type: string
              Default: ""

              Defines an alternate host name to verify the server  certificate
              against.   This  should  not be set unless you are sure what you
              are doing, but it might be useful for  connection  to  a  .onion
              host without a properly configured host name in the certificate.
              See $ssl_verify_host.



       ssl_verify_partial_chains
              Type: boolean
              Default: no

              This option should not be changed from the  default  unless  you
              understand what you are doing.

              Setting  this variable to yes will permit verifying partial cer-
              tification chains, i. e. a certificate chain where not the root,
              but an intermediate certificate CA, or the host certificate, are
              marked trusted (in $certificate_file), without marking the  root
              signing CA as trusted.

              (OpenSSL 1.0.2b and newer only).



       ssl_ciphers
              Type: string
              Default: "ALL:!aNULL:!eNULL:!EXPORT:!LOW:!MD5:!DES:!3DES:!RC2:!RC4:!PSK:!kDH"

              Contains  a  colon-separated  list  of ciphers to use when using
              SSL.  For OpenSSL, see ciphers(1) for the syntax of the string.

              For GnuTLS, this option will be used in place of "NORMAL" at the
              start  of  the priority string.  See gnutls_priority_init(3) for
              the syntax and more details.  (Note:  GnuTLS  version  2.1.7  or
              higher is required.)



       status_chars
              Type: string
              Default: "-*%A"

              Controls  the  characters  used  by  the "%r" indicator in $sta-
              tus_format. The first character is  used  when  the  mailbox  is
              unchanged. The second is used when the mailbox has been changed,
              and it needs to be resynchronized. The  third  is  used  if  the
              mailbox  is  in  read-only  mode,  or if the mailbox will not be
              written when exiting that mailbox (You  can  toggle  whether  to
              write  changes  to  a mailbox with the <toggle-write> operation,
              bound by default to "%"). The fourth is used  to  indicate  that
              the current folder has been opened in attach- message mode (Cer-
              tain operations like composing a new mail, replying, forwarding,
              etc. are not permitted in this mode).



       status_format
              Type: string (localized)
              Default: "-%r-Mutt: %f [Msgs:%?M?%M/?%m%?n? New:%n?%?o? Old:%o?%?d? Del:%d?%?F? Flag:%F?%?t? Tag:%t?%?p? Post:%p?%?b? Inc:%b?%?B? Back:%B?%?l? %l?]---(%s/%S)-%>-(%P)---"

              Controls  the format of the status line displayed in the "index"
              menu.  This string is similar to $index_format, but has its  own
              set of printf(3)-like sequences:
              %b     number of mailboxes with new mail *
              %B     number of backgrounded editing sessions *
              %d     number of deleted messages *
              %f     the full pathname of the current mailbox
              %F     number of flagged messages *
              %h     local hostname
              %l     size  (in  bytes)  of  the  current  mailbox (see format-
                     strings-size) *
              %L     size (in bytes) of the messages shown (i.e., which  match
                     the current limit) (see formatstrings-size) *
              %m     the number of messages in the mailbox *
              %M     the  number of messages shown (i.e., which match the cur-
                     rent limit) *
              %n     number of new messages in the mailbox *
              %o     number of old unread messages *
              %p     number of postponed messages *
              %P     percentage of the way through the index
              %r     modified/read-only/won't-write/attach-message  indicator,
                     according to $status_chars
              %R     number of read messages *
              %s     current sorting mode ($sort)
              %S     current aux sorting method ($sort_aux)
              %t     number of tagged messages *
              %u     number of unread messages *
              %v     Mutt version string
              %V     currently active limit pattern, if any *
              %>X    right justify the rest of the string and pad with "X"
              %|X    pad to the end of the line with "X"
              %*X    soft-fill with character "X" as pad

              For  an  explanation of "soft-fill", see the $index_format docu-
              mentation.

              * = can be optionally printed if nonzero

              Some of the above sequences can be used to  optionally  print  a
              string  if  their  value  is nonzero.  For example, you may only
              want to see the number of  flagged  messages  if  such  messages
              exist, since zero is not particularly meaningful.  To optionally
              print a string based upon one of the above sequences,  the  fol-
              lowing construct is used:

              %?<sequence_char>?<optional_string>?

              where  sequence_char  is  a  character from the table above, and
              optional_string  is  the  string  you  would  like  printed   if
              sequence_char  is  nonzero.   optional_string  may contain other
              sequences as well as normal text, but you may not nest  optional
              strings.

              Here is an example illustrating how to optionally print the num-
              ber of new messages in a mailbox:

              %?n?%n new messages.?

              You can also switch between two strings using the following con-
              struct:

              %?<sequence_char>?<if_string>&<else_string>?

              If  the  value  of  sequence_char is non-zero, if_string will be
              expanded, otherwise else_string will be expanded.

              You can force the result of any printf(3)-like  sequence  to  be
              lowercase by prefixing the sequence character with an underscore
              ("_") sign.  For example, if you want to display the local host-
              name in lowercase, you would use: "%_h".

              If  you prefix the sequence character with a colon (":") charac-
              ter, mutt will replace any dots in the expansion by underscores.
              This  might be helpful with IMAP folders that don't like dots in
              folder names.



       status_on_top
              Type: boolean
              Default: no

              Setting this variable causes the "status bar" to be displayed on
              the  first  line  of  the screen rather than near the bottom. If
              $help is set, too it'll be placed at the bottom.



       strict_threads
              Type: boolean
              Default: no

              If set, threading will only make use of  the  "In-Reply-To"  and
              "References:"  fields  when  you  $sort  by message threads.  By
              default, messages with the same subject are grouped together  in
              "pseudo  threads.". This may not always be desirable, such as in
              a personal mailbox where you might have several  unrelated  mes-
              sages  with  the  subjects  like  "hi"  which  will  get grouped
              together. See also $sort_re for a less drastic way  of  control-
              ling this behavior.



       suspend
              Type: boolean
              Default: yes

              When unset, mutt won't stop when the user presses the terminal's
              susp key, usually "^Z". This is useful if you run mutt inside an
              xterm using a command like "xterm -e mutt".



       text_flowed
              Type: boolean
              Default: no

              When  set, mutt will generate "format=flowed" bodies with a con-
              tent type of "text/plain; format=flowed".  This format is easier
              to  handle  for  some mailing software, and generally just looks
              like ordinary text.  To actually make use of this format's  fea-
              tures, you'll need support in your editor.

              The  option  only  controls  newly composed messages.  Postponed
              messages, resent messages, and draft messages  (via  -H  on  the
              command line) will use the content-type of the source message.

              Note that $indent_string is ignored when this option is set.



       thorough_search
              Type: boolean
              Default: yes

              Affects  the  ~b, ~B, and ~h search operations described in sec-
              tion "patterns".  If set, the headers  and  body/attachments  of
              messages  to be searched are decoded before searching. If unset,
              messages are searched as they appear in the folder.

              Users searching attachments or for non-ASCII  characters  should
              set  this  value  because  decoding  also  includes  MIME  pars-
              ing/decoding and possible character set  conversions.  Otherwise
              mutt will attempt to match against the raw message received (for
              example quoted-printable encoded or with encoded headers)  which
              may lead to incorrect search results.



       thread_received
              Type: boolean
              Default: no

              When  set, mutt uses the date received rather than the date sent
              to thread messages by subject.



       tilde
              Type: boolean
              Default: no

              When set, the internal-pager will pad blank lines to the  bottom
              of the screen with a tilde ("~").



       time_inc
              Type: number
              Default: 0

              Along  with  $read_inc,  $write_inc, and $net_inc, this variable
              controls the frequency with  which  progress  updates  are  dis-
              played.  It  suppresses updates less than $time_inc milliseconds
              apart. This can improve throughput on systems with  slow  termi-
              nals, or when running mutt on a remote system.

              Also see the "tuning" section of the manual for performance con-
              siderations.



       timeout
              Type: number
              Default: 600

              When Mutt is waiting for user input either idling in menus or in
              an  interactive prompt, Mutt would block until input is present.
              Depending on the context, this would prevent certain  operations
              from working, like checking for new mail or keeping an IMAP con-
              nection alive.

              This variable controls how many seconds Mutt will at  most  wait
              until it aborts waiting for input, performs these operations and
              continues to wait for input.

              A value of zero or less will cause Mutt to never time out.



       tmpdir
              Type: path
              Default: ""

              This variable allows you to specify where Mutt  will  place  its
              temporary  files  needed  for displaying and composing messages.
              If this variable is not set, the environment variable $TMPDIR is
              used.  If $TMPDIR is not set then "/tmp" is used.



       to_chars
              Type: string
              Default: " +TCFL"

              Controls  the  character used to indicate mail addressed to you.
              The first character is  the  one  used  when  the  mail  is  not
              addressed  to your address.  The second is used when you are the
              only recipient of the message.  The third is when  your  address
              appears  in  the  "To:"  header  field, but you are not the only
              recipient of the message.  The fourth  character  is  used  when
              your address is specified in the "Cc:" header field, but you are
              not the only recipient.  The fifth character is used to indicate
              mail that was sent by you.  The sixth character is used to indi-
              cate when a mail was sent to a mailing-list you subscribe to.



       trash
              Type: path
              Default: ""

              If set, this variable specifies the path  of  the  trash  folder
              where  the  mails  marked for deletion will be moved, instead of
              being irremediably purged.

              NOTE: When you delete a message  in  the  trash  folder,  it  is
              really deleted, so that you have a way to clean the trash.



       ts_icon_format
              Type: string (localized)
              Default: "M%?n?AIL&ail?"

              Controls  the format of the icon title, as long as "$ts_enabled"
              is set.  This string is identical in formatting to the one  used
              by "$status_format".



       ts_enabled
              Type: boolean
              Default: no

              Controls  whether mutt tries to set the terminal status line and
              icon name.  Most terminal emulators emulate the status  line  in
              the window title.



       ts_status_format
              Type: string (localized)
              Default: "Mutt with %?m?%m messages&no messages?%?n? [%n NEW]?"

              Controls  the  format  of  the  terminal  status line (or window
              title), provided that "$ts_enabled" has been set. This string is
              identical in formatting to the one used by "$status_format".



       tunnel
              Type: string
              Default: ""

              Setting  this  variable will cause mutt to open a pipe to a com-
              mand instead of a raw socket. You may be able to use this to set
              up  preauthenticated  connections to your IMAP/POP3/SMTP server.
              Example:


              set tunnel="ssh -q mailhost.net /usr/local/libexec/imapd"


              Note: For this example to work you must be able to log in to the
              remote machine without having to enter a password.

              When  set,  Mutt  uses  the  tunnel  for all remote connections.
              Please see "account-hook" in the manual for how to use different
              tunnel commands per connection.



       tunnel_is_secure
              Type: boolean
              Default: yes

              When  set, Mutt will assume the $tunnel connection does not need
              STARTTLS to be enabled.  It will also allow IMAP PREAUTH  server
              responses  inside  a  tunnel to proceed.  This is appropriate if
              $tunnel uses ssh or directly invokes the server locally.

              When unset,  Mutt  will  negotiate  STARTTLS  according  to  the
              ssl_starttls  and  ssl_force_tls variables.  If ssl_force_tls is
              set, Mutt will abort connecting if an IMAP server responds  with
              PREAUTH.   This  setting is appropriate if $tunnel does not pro-
              vide security and could be tampered with by attackers.



       uncollapse_jump
              Type: boolean
              Default: no

              When set, Mutt will jump to the next  unread  message,  if  any,
              when the current thread is uncollapsed.



       uncollapse_new
              Type: boolean
              Default: yes

              When  set,  Mutt  will  automatically  uncollapse  any collapsed
              thread that  receives  a  new  message.  When  unset,  collapsed
              threads  will  remain collapsed. the presence of the new message
              will still affect index sorting, though.



       use_8bitmime
              Type: boolean
              Default: no

              Warning: do not set this variable unless you are using a version
              of sendmail which supports the -B8BITMIME flag (such as sendmail
              8.8.x) or you may not be able to send mail.

              When set, Mutt will invoke $sendmail with  the  -B8BITMIME  flag
              when sending 8-bit messages to enable ESMTP negotiation.



       use_domain
              Type: boolean
              Default: yes

              When  set,  Mutt  will qualify all local addresses (ones without
              the "@host" portion) with the value of $hostname.  If unset,  no
              addresses will be qualified.



       use_envelope_from
              Type: boolean
              Default: no

              When  set, mutt will set the envelope sender of the message.  If
              $envelope_from_address is set, it will be  used  as  the  sender
              address.  If  unset, mutt will attempt to derive the sender from
              the "From:" header.

              Note that this information is passed to sendmail  command  using
              the -f command line switch. Therefore setting this option is not
              useful if the $sendmail variable already contains -f or  if  the
              executable  pointed  to  by  $sendmail  doesn't  support  the -f
              switch.



       use_from
              Type: boolean
              Default: yes

              When set, Mutt will generate the "From:" header field when send-
              ing  messages.  If unset, no "From:" header field will be gener-
              ated unless the user explicitly sets one using the "my_hdr" com-
              mand.



       use_ipv6
              Type: boolean
              Default: yes

              When set, Mutt will look for IPv6 addresses of hosts it tries to
              contact.  If this option is unset, Mutt will restrict itself  to
              IPv4 addresses.  Normally, the default should work.



       user_agent
              Type: boolean
              Default: no

              When  set, mutt will add a "User-Agent:" header to outgoing mes-
              sages, indicating which version of mutt was used  for  composing
              them.



       visual
              Type: path
              Default: ""

              Specifies  the  visual editor to invoke when the "~v" command is
              given in the built-in editor.



       wait_key
              Type: boolean
              Default: yes

              Controls whether Mutt will ask you  to  press  a  key  after  an
              external   command   has   been   invoked  by  these  functions:
              <shell-escape>, <pipe-message>,  <pipe-entry>,  <print-message>,
              and <print-entry> commands.

              It  is also used when viewing attachments with "auto_view", pro-
              vided that the corresponding mailcap entry has  a  needsterminal
              flag, and the external program is interactive.

              When  set, Mutt will always ask for a key. When unset, Mutt will
              wait for a key only if the external command returned a  non-zero
              status.



       weed
              Type: boolean
              Default: yes

              When set, mutt will weed headers when displaying, forwarding, or
              replying to messages.

              Also       see       $copy_decode_weed,       $pipe_decode_weed,
              $print_decode_weed.



       wrap
              Type: number
              Default: 0

              When set to a positive value, mutt will wrap text at $wrap char-
              acters.  When set to a negative value, mutt will  wrap  text  so
              that there are $wrap characters of empty space on the right side
              of the terminal. Setting it to zero makes mutt wrap at the  ter-
              minal width.

              Also see $reflow_wrap.



       wrap_headers
              Type: number
              Default: 78

              This  option specifies the number of characters to use for wrap-
              ping an outgoing message's headers. Allowed values  are  between
              78 and 998 inclusive.

              Note:  This  option usually shouldn't be changed. RFC5233 recom-
              mends a line length of 78 (the default), so please  only  change
              this setting when you know what you're doing.



       wrap_search
              Type: boolean
              Default: yes

              Controls whether searches wrap around the end.

              When  set,  searches  will wrap around the first (or last) item.
              When unset, incremental searches will not wrap.



       wrapmargin
              Type: number
              Default: 0

              (DEPRECATED) Equivalent to setting $wrap with a negative value.



       write_bcc
              Type: boolean
              Default: no

              Controls whether mutt writes out the "Bcc:" header when  prepar-
              ing  messages  to be sent.  Some MTAs, such as Exim and Courier,
              do not strip the "Bcc:" header; so it is advisable to leave this
              unset  unless you have a particular need for the header to be in
              the sent message.

              If mutt is set to deliver directly  via  SMTP  (see  $smtp_url),
              this  option  does nothing: mutt will never write out the "Bcc:"
              header in this case.

              Note this option only affects the sending of  messages.   Fcc'ed
              copies of a message will always contain the "Bcc:" header if one
              exists.



       write_inc
              Type: number
              Default: 10

              When  writing  a  mailbox,  a  message  will  be  printed  every
              $write_inc  messages  to indicate progress.  If set to 0, only a
              single message will be displayed before writing a mailbox.

              Also see the $read_inc, $net_inc and $time_inc variables and the
              "tuning" section of the manual for performance considerations.
