Log tracking MTA option

Log Tracking Information
The  MTA option controls logging of message tracking/recall information. Bit 0 (value 0), if set, includes the tracking id and the current tracking in transaction log entries. The two appear as a single field; the id appears first and is separated from the timeout value by a colon. Tracking information appears immediately after the envelope id and before the  deferred delivery time. An " " attribute is used in XML or JSON format (  set to 4 or 5, respectively).

Normally the  attribute only appears in XML or JSON format logs if there is tracking information to log. As of MS 8.0.2.3, setting bit 2 (value 4) will cause the attribute to appear unconditionally.

If bit 1 (value 2) is set in the  MTA option, then the tracking id and timeout, again separated by a colon, appear in the    mapping table probe, again immediately after the  envelope id and before the  deferred delivery time.
