Ldap url result mapping MTA option

Direct LDAP attribute name MTA options:  (LDAP attribute name)
The  MTA option names an LDAP attribute  which may be placed on a group entry in LDAP for purposes of manipulating the results of lookups of the   and   attributes (or more precisely, the attributes named by the   and   MTA options), and as of Messaging Server 7.0-5, also   (the attributes named by the   and   MTA options). Currently there is no default value (default attribute) for  ; to use this feature, you must choose a (new) attribute and add it to the schema (or disable schema checking).

This attribute&#x27;s value should name an MTA mapping table to be applied to any resulted returned by expanding either a   or a    attribute, or as of Messaging Server 7.0-5 also a   attribute as well as any custom attribute named by. The mapping probe will be of the form: LDAP-URL&#x7c;LDAP-result where  is the (literal string) value of the ,  , or    attribute itself (or custom attribute named by  ), and   is the value returned from LDAP for that   query. If the mapping returns with  set, then the mapping result string will replace the LDAP result for alias processing purposes. If the mapping returns with   set, then the result will be skipped.

In particular, this mechanism can be used to define groups based on attributes that don&#x27;t contain proper email addresses.
