Public bug reported:
I'm trying to setup a combination IMAP/SMTP server using Dovecot and
Postfix on a 20.04 system. After attempting to setup SASL
authentication for postfix, the system fails with a postfix/smtpd:
fatal: no SASL authentication mechanisms whenever any SMTP connection is
attempted (either via a program like Thunderbird or telnet localhost
25). I'm trying to use the guide at
https://ubuntu.com/server/docs/mail-postfix, but even with some of the
debug settings enabled, I'm still not seeing a more useful log message.
What's wrong?
My configuration:
