Autoreply timeout default MTA option

Autoresponse periodicity MTA options:  (non-negative integer)
The  MTA option specifies the default duration, in hours, for successive vacation (autoreply) responses to any given sender. This system-wide value specifies a default both for  actions specified explicitly in Sieve filters, and for implicit " " effects resulting from  LDAP   attributes.

This sytem-wide default may be overridden in explicit " " actions in Sieve filters by specifying a desired timeout via a  " ", " ", or " " parameter. Or for implicit " " actions generated due to LDAP  attributes, this sytem-wide default may be overridden on a per-domain basis via the domain attribute named by the    MTA option, or on a  per-user basis via the user attribute (normally  ) named by the    MTA option. The default for this option is 168 (i.e., 7&#x2a;24), meaning that vacation messages would only be sent back to a given sender once a week (no matter how many messages the sender sends).
