The changes you made in mm_cfg.py

REPLY_TO_ADDRESS = '<acceptable host/domain>'

have nothing to do with this issue. First, they only set defaults for
new lists. They have no effect on existing lists. Second, they only
have to do with a Reply-To: header in outgiong list posts which has
absolutely nothing to do with your problem.

Lots of reasons. It could be a relaying issue which can't be detected
until the MTA knows the destination, or it could just be that the MTA
is configured to do the FROM domain check at RCPT time in the SMTP

What is the exact reject response from the MTA?

What is the difference between 'non-Mailman' mail that works and
Mailman mail that doesn't. Does the non-Mailman mail come from a
different envelope from domain? Does non-Mailman mail use SMTP-AUTH to
authenticate to the ISP?
