Ldap domain attr blocklimit MTA option

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  to users in the domain. The default LDAP attribute name is.

The effect of the attribute named by  is a destination (recipient) analogue of the effect of  whatever attribute is named by   MTA option, which limits the size of message that may be sent by users in the domain. The attribute named by  may also be considered as the domain-level analogue of the user-level   attribute (or whatever attribute is named by the   MTA option) and group   attribute (or whatever attribute is named by the   MTA option).

New in MS 6.3, this attribute is also checked during   lookups, and will be used (for messages that have no return-of-content policy already set) to decide whether the NOTARY non-return-of-content flag should be set.

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.)
