I use postfix 2.3 with cyrus-sasl for smtp-auth cyrus-sasl needs a restart every few hours ( they havent fixed the memory leaks )
The problem is if saslauthd is momentarily unavailable , postfix cant (obviously) authenticate the smtp session. Postfix rejects the mail with a permanent failure. How do I change this to a 4xx error code so that the clients server would retry the mail Thanks Ram
