[Question] Remove These Headers and Outlook conversation view

[Shawn Iverson]

The problem you are having is expected.  When MailWatch releases from
quarantine using sendmail, it is literally feeding the entire message +
header as-is into the MTA queue.  The MTA isn't going to generate a new
message id.  It is not being reconstructed when released in this fashion.
