Ldap domain attr sourceblocklimit MTA options

Direct LDAP attribute name MTA options:  (LDAP attribute name(s))
The  MTA option specifies the name of an LDAP attribute  -- or a list of such names -- used to store a size limit on messages sent by users in the domain.

The effect of the attribute named by  is a source (sending) analogue of the effect of the   attribute (or whatever attribute is named by  ), which limits the size of message that may be received by users in the domain. The attribute named by  may also be considered as the domain-level analogue of the user-level attribute named by.

A new effect in MS 6.3-0.15 is that a per-domain setting such as this will override more general settings (and a per-user setting will override even a per-domain setting), rather than (as previously) the minimum of all applicable limits being applied. Thus new in MS 6.3-0.15, users in a particular domain maybe allowed to send large messages as an exception to more general, smaller limits, by setting a large value for this domain attribute while a general smaller limit (such as that set via the  channel option) remains in effect.

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