I think it has to do with the way SpamAssassin and ClamAV are integrated 
with Mailman as handlers.  I think they can't handle the attachment.

This whole thing really bothered me a couple of days ago because it appeared 
that after this mp3 attachment was sent, then SA and ClamAV never processed 
any further email until they were restarted.  However, this observation is 
no longer reproducible (thankfully!), so things are OK.

I still don't know why the attachment passes now, when content filtering has 
been OFF all along.

Oh well - CASE CLOSED for now.  Thanks for the discussion.  - John
