Yes, I know. I was just about to resend. It is attached here. The MUA I
used to send the previous message gives any attachment without an
extension Content-Type: application/octet-stream, so the list's content
filtering removed it.

If we're going to do something like this going forward, we can certainly
change the queue. For this 'debug' effort, I wanted to keep it simple
and use an existing mm_cfg queue name.
