Ldap sourceblocklimit MTA option

Direct LDAP attribute name MTA options:  (LDAP attribute name)
The  MTA option specifies the name of a user or group LDAP attribute used to store a  sending-user-specific maximum message size, analogous to the    channel option. There is no default, (no pre-defined LDAP attribute for this purpose); if desiring to have the exact same sending limit as receiving limit, then the   MTA option could be set to the same value as the   MTA option, which by default is.

New behavior in MS 6.3-0.15 is that a per-user setting such as the value of the LDAP attribute named by  will override more general settings, rather than (as previously) the minimum of all applicable limits being applied; thus new in MS 6.3-0.15, a particular user can be allowed to send large messages as an exception to more general, smaller limits, by setting a large value for this attribute while general small limits remain in effect.

(Note also that the    channel option, if used, may modify the timing and form of rejections due to exceeding message size constraints.)
