Dear List Last time I have configured postfix was many years ago with version 2.3. Now I wish to upgrade to 2.7 and also change configuration by adding dovecot sasl authentication. It is working as expected. Public can deliver mail to my domain without authentication. authenticated users can use the server as a relay to anywhere.
My concern is that with my config if dovecot server were to go down for any reason at all postfix cannot accept mail delivery. This seems to be undesirable because mail delivery does not need authentication. I believe the following line in main.cf might be relevant. smtpd_recipient_restrictions = permit_mynetworks, permit_sasl_authenticated, reject_unauth_destination Is the other option setting up 2 postfix servers: 1 for mail delivery and 1 for authenticated relay? Thanks for any suggestion. mr.wu
