Ldap domain root MTA option

Direct LDAP schema MTA options:  (DN)
The  MTA option specifies, for MTA purposes,  the base DN for the domain portion of the DIT. This option, if set, overrides (for MTA purposes) the base option  (or in legacy configuration, the configutil parameter  ). If neither the MTA option nor the  base option (in legacy  configuration,  the configutil parameter) has been explicitly set, then the default is.
