I get this error in mail.log when I try to send mail to my domain Recipient address rejected: SMTP AUTH is required for users under this sender domain (in reply to RCPT TO command)). My setup is such that the server hosting the mailman3 (lists@tld) lists is different from the mail server (mail@tld) Please advise.
This is an MTA configuration issue. The mail@tld MTA needs to deliver list mail via LMTP to Mailman's LMTP runner at lists@tld or alternatively via SMTP to an MTA at lists@tld which relays via LMTP to Mailman.
We can't begin to advise you without knowing more detail about the MTA(s) configuration.
