Hello everyone, I have a mail server configured with Postfix, Dovecot + Spamassassin. Mail comes in just fine on port 25 filtered by spamassassin. Postfix uses dovecot to route to spamassassin: Here' s a problem: our users send mail via plain 25, SSL and TLS. Sending via SSL and TLS is no problem, because -o content_filter=spamassassin isn't configure for 587 and 465, postfix does direct smtp delivery. But when users send via port 25, it gets filtered by SA, which returns all external users as " status=bounced (user unknown)" according to maillog. Hence anyone who tries to send via 25 gets a bounce back. What am I missing to make this work? Thanks
