MTA support for AXS:One archiving

(New MS 6.3) The MTA has support for use with the AXS:One archive facility. AXS:One operates by scanning a directory for files to archive, so the MTA writes copies of the messages to be  archived, in a special AXS:One format (in particular including a  hash "identifier"  for each copy of a message delivered to the  Message Store), to this specified special directory (for AXS:One to  then "pick up"). (The AXS:One archive facility will generate a message identifier itself for messages that it finds without one, and  this is sufficient for copies of messages that were delivered to  external Internet sites. The presence of an identifier generated by the  MTA on copies of messages delivered to the Message Store is instead  important for correlation of the archived message copies with the  message copies actually in the Message Store.)

Note that the MTA&#x27;s generic facilities to generate and add an "identifer" to messages may be useful with other forms of  archiving as well; see  Message identifier generation,  as well as the    channel options, and Message archival  and hashing MTA options, for further discussion of the generation and  addition to messages of such an identifying "hash" value.

While archiving is most often configured for all users and messages, it is possible to configure archiving only for certain sets of users,  using the sorts of "opt-in" approaches (per-user  "opt-in" LDAP attribute or channel-level "opt-in")  available  with the MTA&#x27;s general spam/virus filter package integration approach  (of which the MTA&#x27;s AXS:One integration is one instance). See the    MTA options,  the      channel options, and the (new in MS 6.3)      MTA options.

When    based triggering of archiving on a  per-sending-user basis is desired, note that this is triggered during  address reversal,  and hence it is critical to be performing address  reversal, and in particular properly configured address reversal. See Intended side effects of LDAP address reversal.
