Hi, i'm having problems with postfix and dovecot setup. I want it to work like this: 1. postfix/dovecot checks if a specific system user exsts 2. ok: systemuser exists - mail is delivered to ~/Maildir 3. fail: systemuser doesn't exists - check if it's a virtual user 4. ok: virtualuser exists - mail is delivered to /home/vmail/<domain>/<user> (format: Maildir) 5. fail: it's not a systemuser or virtualuser - return 550 error And i don't know how exacly configure postfix and dovecot as a LDA... I think further configuration to use Amavis and Spamassassin shouldn't hard but now i'm stuck on postfix and dovecot.
