Bounced message not detected as bounce

[Bug Importer]

SMTP Server ID: 220 csd.k12.nh.us FirstClass ESMTP Mail Server v5.50 ready

Response from mail sent to invalid user[<email address hidden>]
is not interpretted as a bounce and instead is sent to the list for
delivery. (Good thing only subscribers can post or else a large mailstorm
would have ensued).

A copy of the bounce message follows:

I'm closing this because MM2.1 has much improved bounce
processing, and because it's a royal pain to grok out the
original bounce message when it was pasted in instead of
attached.
