[Mailman-Users] Mail Processing Problem?

Thanks for the reply.

I'll remove those changes.

The exact response is:

550 [PERMFAIL] bellsouth.net requires valid sender domain (in reply to
RCPT TO command))

I should have paid more attention, sorry. Is not the RCPT TO command
itself but the reply to it and I believe it is referring to my
mailman/SMTP server.

I  can't tell you the specific difference because there are no useful
messages (just a 250 sent message) when it is successful. My main
point was that a message formed by the 'mail' command, on the same
server, works so it seems a mailman config issue. I don't think
SMTP-AUTH matters since both go through the same local 'SMTP'  server
to the same ISP mail server. Right? Isn't the mechanism 'sendmail' in
both cases to my SMTP server? Or is 'mailman' trying to talk directly
to my ISP's mail server? I don't recall doing anything special with
mailman when it was working for my ISP's mail server. I may have done
something to 'postfix' specifically for mailman but I don't recall
what.

The changes you made in mm_cfg.py

DEFAULT_REPLY_GOES_TO_LIST = 2
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
transaction.

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?
