Capture domain replace MTA option

Direct LDAP MTA options:  (0-2)
Normally the effects of domain-level capture LDAP attributes (as specified by the  MTA option) and user-level capture LDAP attributies (as specified by the   MTA option) are cumulative, that is, message copies are sent to all such capture/journal recipients.

The new-in 8.0.1.3  MTA option changes this behavior. If set to a positive value, it will change the behavior of the first   attributes so that domain-level capture addresses are replaced rather than being combined with user-level attributes.

The default value of 0 disables replacement.

Note that the special attribute value "&#x2a;" can be used as a "null" capture address. This makes it possible to disable domain-level capture on a per-user basis.
