My setup is Postfix with SASL and TLS, cyrus-imapd with TLS, and
roundcube mail.
Everything was working fine until I changed a few things trying to
avoid becoming an open relay and also to reject as much spam as
possible.
Now roundcube is not allowed to send mail. It was fine before. If I
use any other Desktop client, it works fine, but not with roundcube
mail.
How can I fix this?
The log:
