Hi.

Did anyone figure out the issue or have a working configuration with this:

https://lists.mailman3.org/archives/list/mailman-users@mailman3.org/message/...

I am getting the same error, with the same configuration.

Issue: Postfix LMTP does not pass messages onto MM3:LMTP. Instead the behavior summary is as follows:

Jul  3 11:56:30 mail1 postfix/lmtp[824956]: 5168B20017A: to=<lmtp:[127.0.0.1]:8024@domain.com>, orig_to=<testing@domain.com>, relay=mail1.domain.com[private/dovecot-lmtp], delay=0.08, delays=0.03/0.01/0.02/0.01, dsn=5.1.1, status=bounced (host mail1.domain.com[private/dovecot-lmtp] said: 550 5.1.1 <"lmtp:[127.0.0.1]:8024"@domain.com> User doesn't exist: lmtp:[127.0.0.1]:8024@domain.com (in reply to RCPT TO command))

thanks,

Geoff
