Log delivery flags MTA option

Transaction logging MTA options:  (bitmask)
New in 7.0.5. The  MTA option causes a field recording  delivery flag bits (recorded as an integer) in  MTA message transaction log file entries  and/or  LOG_ACTION mapping table probes. Bit 0 (value 1) enables including the field in MTA message transaction log file entries; bit 1 (value 2) enables including the field in   mapping table probes.

If enabled, this field appears after the IMAP flags field (  MTA option). The XML format tag for this field is " ". The default in non-XML format logging is 0; the default when XML format is enabled is 1.

Bits 0 (value 1) and 1 (value 2) of the logged field roughly correspond to those in the  channel option. The other bits in this value are intentionally undocumented.
