The smtp-failure entries give more info about the same event.

The outgoing MTA is 'hanging up' on Mailman during SMTP delivery from
Mailman. This may be because of something it doesn't like about a
recipient or some other reason. It should not be doing DNS validation,
spam scanning or any such things on messages coming from Mailman. That
is a real performance killer. See the relevant hits from
<http://www.python.org/cgi-bin/faqw-mm.py?query=performance&querytype=simple&casefold=yes&req=search>.

If your Python is 2.4 or later, see
<http://www.python.org/cgi-bin/faqw-mm.py?req=show&file=faq04.073.htp>
for a way to get debugging information from Python's smtplib.
