SENDMAIL(1)                 General Commands Manual                SENDMAIL(1)



NAME
       sendmail - Postfix to Sendmail compatibility interface

SYNOPSIS
       sendmail [option ...] [recipient ...]

       mailq
       sendmail -bp

       newaliases
       sendmail -I

DESCRIPTION
       The Postfix sendmail(1) command implements the Postfix to Sendmail com-
       patibility interface.  For the  sake  of  compatibility  with  existing
       applications,  some  Sendmail  command-line  options are recognized but
       silently ignored.

       By default, Postfix sendmail(1) reads a  message  from  standard  input
       until  EOF  or  until  it  reads  a  line  with only a . character, and
       arranges for delivery.  Postfix sendmail(1) relies on  the  postdrop(1)
       command to create a queue file in the maildrop directory.

       Specific  command aliases are provided for other common modes of opera-
       tion:

       mailq  List the mail queue. Each entry shows the queue file ID, message
              size,  arrival  time, sender, and the recipients that still need
              to be delivered.  If mail could not be delivered upon  the  last
              attempt, the reason for failure is shown. The queue ID string is
              followed by an optional status character:

              *      The message is in the active queue, i.e. the  message  is
                     selected for delivery.

              !      The  message is in the hold queue, i.e. no further deliv-
                     ery attempt will be made until  the  mail  is  taken  off
                     hold.

              This   mode   of  operation  is  implemented  by  executing  the
              postqueue(1) command.

       newaliases
              Initialize the alias database.  If no input  file  is  specified
              (with  the  -oA  option,  see  below), the program processes the
              file(s) specified with the alias_database configuration  parame-
              ter.   If  no alias database type is specified, the program uses
              the type specified with the default_database_type  configuration
              parameter.  This mode of operation is implemented by running the
              postalias(1) command.

              Note: it may take a minute or so before an alias database update
              becomes  visible.  Use the "postfix reload" command to eliminate
              this delay.

       These and other features can be selected by specifying the  appropriate
       combination  of  command-line  options. Some features are controlled by
       parameters in the main.cf configuration file.

       The following options are recognized:

       -Am (ignored)

       -Ac (ignored)
              Postfix sendmail uses the same configuration file regardless  of
              whether or not a message is an initial submission.

       -B body_type
              The message body MIME type: 7BIT or 8BITMIME.

       -bd    Go  into  daemon  mode. This mode of operation is implemented by
              executing the "postfix start" command.

       -bh (ignored)

       -bH (ignored)
              Postfix has no persistent host status database.

       -bi    Initialize alias database. See the newaliases command above.

       -bl    Go into daemon mode. To accept only local  connections  as  with
              Sendmail's  -bl  option, specify "inet_interfaces = loopback" in
              the Postfix main.cf configuration file.

       -bm    Read mail from standard input and arrange for delivery.  This is
              the default mode of operation.

       -bp    List the mail queue. See the mailq command above.

       -bs    Stand-alone  SMTP  server mode. Read SMTP commands from standard
              input, and write responses to standard output.   In  stand-alone
              SMTP  server  mode,  mail relaying and other access controls are
              disabled by default. To enable them,  run  the  process  as  the
              mail_owner user.

              This  mode  of  operation is implemented by running the smtpd(8)
              daemon.

       -bv    Do not collect or deliver a  message.  Instead,  send  an  email
              report  after  verifying each recipient address.  This is useful
              for testing address rewriting and routing configurations.

              This feature is available in Postfix version 2.1 and later.

       -C config_file

       -C config_dir
              The path name of the Postfix main.cf  file,  or  of  its  parent
              directory.  This  information  is  ignored with Postfix versions
              before 2.3.

              With all Postfix versions, you can specify a directory  pathname
              with  the MAIL_CONFIG environment variable to override the loca-
              tion of configuration files.

       -F full_name
              Set the sender full name. This overrides  the  NAME  environment
              variable, and is used only with messages that have no From: mes-
              sage header.

       -f sender
              Set the envelope sender  address.  This  is  the  address  where
              delivery problems are sent to. With Postfix versions before 2.1,
              the  Errors-To:  message  header  overrides  the  error   return
              address.

       -G     Gateway  (relay)  submission, as opposed to initial user submis-
              sion.  Either do not rewrite addresses at all, or update  incom-
              plete  addresses  with  the  domain  information  specified with
              remote_header_rewrite_domain.

              This option is ignored before Postfix version 2.3.

       -h hop_count (ignored)
              Hop count limit. Use the hopcount_limit configuration  parameter
              instead.

       -I     Initialize alias database. See the newaliases command above.

       -i     When  reading  a message from standard input, don't treat a line
              with only a . character as the end of input.

       -L label (ignored)
              The logging label. Use the syslog_name  configuration  parameter
              instead.

       -m (ignored)
              Backwards compatibility.

       -N dsn (default: 'delay, failure')
              Delivery  status  notification  control. Specify either a comma-
              separated list with one or more of  failure  (send  notification
              when  delivery fails), delay (send notification when delivery is
              delayed), or success (send  notification  when  the  message  is
              delivered);  or  specify  never (don't send any notifications at
              all).

              This feature is available in Postfix 2.3 and later.

       -n (ignored)
              Backwards compatibility.

       -oAalias_database
              Non-default alias database. Specify pathname  or  type:pathname.
              See postalias(1) for details.

       -O option=value (ignored)
              Set  the named option to value. Use the equivalent configuration
              parameter in main.cf instead.

       -o7 (ignored)

       -o8 (ignored)
              To send 8-bit or binary content, use an appropriate MIME  encap-
              sulation and specify the appropriate -B command-line option.

       -oi    When  reading  a message from standard input, don't treat a line
              with only a . character as the end of input.

       -om (ignored)
              The sender is never eliminated from alias etc. expansions.

       -o x value (ignored)
              Set option x to value. Use the equivalent configuration  parame-
              ter in main.cf instead.

       -r sender
              Set  the  envelope  sender  address.  This  is the address where
              delivery problems are sent to. With Postfix versions before 2.1,
              the   Errors-To:  message  header  overrides  the  error  return
              address.

       -R return
              Delivery status notification control.  Specify "hdrs" to  return
              only  the header when a message bounces, "full" to return a full
              copy (the default behavior).

              The -R option specifies an upper bound; Postfix will return only
              the  header, when a full copy would exceed the bounce_size_limit
              setting.

              This option is ignored before Postfix version 2.10.

       -q     Attempt to deliver all queued mail. This is implemented by  exe-
              cuting the postqueue(1) command.

              Warning:  flushing  undeliverable mail frequently will result in
              poor delivery performance of all other mail.

       -qinterval (ignored)
              The interval between queue runs. Use the queue_run_delay config-
              uration parameter instead.

       -qIqueueid
              Schedule immediate delivery of mail with the specified queue ID.
              This option is implemented by executing  the  postqueue(1)  com-
              mand, and is available with Postfix version 2.4 and later.

       -qRsite
              Schedule  immediate  delivery of all mail that is queued for the
              named site. This option accepts only site names that are  eligi-
              ble  for the "fast flush" service, and is implemented by execut-
              ing the postqueue(1) command.  See flush(8) for more information
              about the "fast flush" service.

       -qSsite
              This  command  is  not implemented. Use the slower "sendmail -q"
              command instead.

       -t     Extract recipients from message headers. These are added to  any
              recipients specified on the command line.

              With Postfix versions prior to 2.1, this option requires that no
              recipient addresses are specified on the command line.

       -U (ignored)
              Initial user submission.

       -V envid
              Specify the envelope ID for notification by servers that support
              DSN.

              This feature is available in Postfix 2.3 and later.

       -XV (Postfix 2.2 and earlier: -V)
              Variable  Envelope Return Path. Given an envelope sender address
              of the form owner-listname@origin,  each  recipient  user@domain
              receives mail with a personalized envelope sender address.

              By  default,  the personalized envelope sender address is owner-
              listname+user=domain@origin. The default + and = characters  are
              configurable   with  the  default_verp_delimiters  configuration
              parameter.

       -XVxy (Postfix 2.2 and earlier: -Vxy)
              As -XV, but uses x and  y  as  the  VERP  delimiter  characters,
              instead of the characters specified with the default_verp_delim-
              iters configuration parameter.

       -v     Send an email report of the first delivery attempt (Postfix ver-
              sions  2.1 and later). Mail delivery always happens in the back-
              ground. When multiple -v options are given, enable verbose  log-
              ging for debugging purposes.

       -X log_file (ignored)
              Log mailer traffic. Use the debug_peer_list and debug_peer_level
              configuration parameters instead.

SECURITY
       By design, this program is not set-user (or group) id. However, it must
       handle  data  from  untrusted, possibly remote, users.  Thus, the usual
       precautions need to be taken against malicious inputs.

DIAGNOSTICS

       MAIL_DEBUG (value does not matter)
              Enable debugging with an external command, as specified with the
              debugger_command configuration parameter.

       NAME   The  sender full name. This is used only with messages that have
              no From: message header. See also the -F option above.

CONFIGURATION PARAMETERS
       The following main.cf parameters are especially relevant to  this  pro-
