Ldap domain attr recipientlimit MTA option

Direct LDAP attribute name MTA options:  (LDAP attribute name)
The  MTA option specifies the name of a per-domain LDAP attribute, analogous to the per-user   MTA option, the   channel option, and the per-SMTP-server    TCP/IP-channel-specific option.

Compare with the   MTA option which specifies the name of a per-domain LDAP attribute for  controlling a related, but not identifical, effect.

New behavior in MS 6.3 is that a per-domain setting such as this will override more general settings, rather than (as previously) the minimum of all applicable limits being applied; thus new in MS 6.3, a particular domain can be allowed to send messages to many recipients as an exception to more general, smaller limits, by setting a large value for this attribute while general small limits remain in effect.
