If you put the unique message-instance identifiers int the Message-Id
instead of the Subject header, then Postfix logs will contain the queue-id
<-> message-id mapping, and also the delivery time of each queue-id.
Logging the Subject in smtp(8) headers does not accurately disclose
the time of delivery, since the delivery may fail (Yahoo, for example,
often tempfails at ".")... The design you describe is I think flawed,
and you really should use the logs in a more natural way.
