The question is, where is the 'non-delivery' occurring? If the issue is
that the incoming post is not reaching Mailman, we would need more
information to know what is happening and what to do about it. Note
that changes to your MX and incoming mail routing should not affect
Mailman as long as list mail is ultimately delivered to the same local
MTA as before.

If posts are reaching Mailman, being archived but not going out, and
there are errors in Mailman's smtp-failure log, you probably need to


in mm_cfg.py where nnn is the port your outgoing MTA is listening on.

for some more information.
