Mail alias information uses the schema defined by this Internet draft. Until a new schema becomes available, LDAP clients will continue to use this schema for mail alias information.
The original LDAP mail groups schema contains a large number of attributes and object classes. Only two attributes and a single object class are used by LDAP clients. These are listed below.
The mail alias attributes are the following.
( 0.9.2342.19200300.100.1.3 NAME 'mail' DESC 'RFC822 email address for this person' EQUALITY caseIgnoreIA5Match SYNTAX 'IA5String(256)' SINGLE-VALUE ) ( 2.16.840.1.113730.3.1.30 NAME 'mgrpRFC822MailMember' DESC 'RFC822 mail address of email only member of group' EQUALITY CaseIgnoreIA5Match SYNTAX 'IA5String(256)' )
The schema for the mailGroup object class is the following.
( 2.16.840.1.113730.3.2.4 NAME 'mailGroup' SUP top STRUCTURAL MUST mail MAY ( cn $ mailAlternateAddress $ mailHost $ mailRequireAuth $ mgrpAddHeader $ mgrpAllowedBroadcaster $ mgrpAllowedDomain $ mgrpApprovePassword $ mgrpBroadcasterModeration $ mgrpDeliverTo $ mgrpErrorsTo $ mgrpModerator $ mgrpMsgMaxSize $ mgrpMsgRejectAction $ mgrpMsgRejectText $ mgrpNoMatchAddrs $ mgrpRemoveHeader $ mgrpRFC822MailMember ))
