Once again I will plug my favourite network debugging tool: Ethereal, a
fantastic GUI packet-tracing tool.  If you had been running Ethereal
while submitting message to Mailman, you could watch the traffic between
Mailman and qmail in real time, and you would have immediately seen the
553 response from sendmail.  Who needs source code when you can just see
the whole SMTP conversation right there?

(www.ethereal.com, or "apt-get install ethereal" if you're running Debian.)
