Ldap add header MTA option

Direct LDAP attribute name MTA options:   (LDAP attribute name)
The  MTA option specifies the name of the group LDAP attribute, by default , which contains header lines to add to messagtes posted to the list. Such header lines might include, for instance, the List-&#x2a;: header lines suggested in RFC 2369 (URLs for Mail List Commands through Message Headers).

See also the   MTA option, for removing header lines from postings to the group or list.

For groups or lists defined via alias file or alias database (legacy configuration) or alias options  (Unified Configuration), see instead the &#x5b;HEADER_ADDITION&#x5d; alias file named parameter or   alias option, respectively.

Use of  (or whatever LDAP attribute is named by  ) is a very simple approach when  unconditional additional of certain header lines is desired. For more complex requirements, consider setting a Sieve filter on the group or list (see the  MTA option) that makes use of the  Sieve editheader extension.
