Log imap flags MTA option

Logging IMAP flags: (bitmask)
New in 7.0.5. The  MTA option causes a field recording  IMAP flags (those set by the MTA)  to be included in  MTA message transaction log file entries  and/or    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 conversion tag field (  option). The XML format tag for this field is "if". The default in non-XML format logging is 0; the default when XML format  is enabled is 1.
