This happens when you run the command as user/group root. What happens
when Exim runs it? If exim (or you) runs it as group 'mail', it should
be fine.

No, that is probably not the reason since the '$MM_PREFIX/mail/mailman
post' script is run for an incoming post and the smtp-failure message
above is related to an attempt by Mailman to send some message
(generated by mailman judging from the msgid) to you. Mailman is
unable to connect to the outgoing MTA via SMTP. If you haven't changed
SMTPHOST and SMTPPORT from their defaults in Defaults.py, this means
Mailman can't connect to 'localhost' port 25. This is probably an Exim
or system configuration issue, not a Mailman problem per se.
