My setup is virtual users in a postfixadmin database. Dovecot does all
authentication, even with posfix. I believe the config snippets I have
included below are the relevant things that make it possible for postfix
to talk to dovecot for mail delivery and authentication.
Mail sent from localhost on port 25 does not require authentication on
my system, because 127.0.0.0/8 is in postfix's mynetworks config and
port 25's access restrictions include permit_mynetworks. Anything sent
via submission (port 587) does require auth, even from trusted
networks. If you can configure your webmail to use submission instead
of smtp, maybe that can be authenticated. You'll need to consult
support resources for your webmail to see if that is possible. I can
say for sure that roundcube can do it ... I have roundcube configured to
talk to port 587, which as mentioned, ALWAYS requires authentication.
When postfix sends mail to dovecot for delivery, I'm pretty sure that
happens without authentication. It's LMTP via unix socket, not
something an outside client can access directly.
Thank you. that's good suggestion.
