Troubleshooting the CAL mail system

tracking who was responsible for authenticated SMTP

If a message shows up that was spam, but was sent through sedna's submission interface (which requires SMTP AUTH), we probably should verify where it came from. By default, postfix does not log AUTH'ed connections to the headers of the message, but grepping through sedna's /var/log/mail.log for the ESMTP ID (in the message's first Received: header) should show exactly how and when the authentication happened. Note that this will only work for messages submitted through the submission interface, and not for messages generated in other ways.
