inetMailGroup

Definition

Identifies mail users allowed to send messages to the mail group. The purpose of this attribute is to restrict who can send messages to the mail group. If no instances of this attribute exist on the inetMailGroup entry, there are no restrictions on who can send messages to the mail group unless the mgrpAllowedDomain, mgrpDisallowedDomain, and mgrpDisAllowedBroadcaster attributes are used.

The Messaging Server expects this attribute to contain either a distinguished name or an RFC822address using an LDAP URI or a mailto address (see example). If a distinguished name is used, it must represent a mailable entry or entries of type group or groupOfUniqueNames. (That is, the group entry must contain an email address in one of the following attributes: mail, mailAlternateAddress, mailEquivalentAddress.)

If multi-valued, each URL or DN is expanded into a list of addresses and each address is checked against the current envelope “from” address. The message is allowed if there is a match.

Any email addresses specified are expanded as if they are a mailing list. Unlike a mailing list, this expansion includes all the attributes used to store email addresses (normally mail, mailAlternateAddress, and mailEquivalentAddress). Thus, if an address for the list itself is specified as a mgrpAllowedBroadcaster, a user can subscribe to a restricted list using one address and use an alternate address to send messages to the list.

If none of the attribute values is a valid URL, or none of the members of the group specified in the attribute value have a valid URL, the message will bounce or be directed to a moderator (as determined by the mgrpMsgRejectAction attribute).

LDAP_AUTH_URL is the MTA option used to specify a different attribute name for this function.
