Postfix relay control is set up as follows: mynetworks = 10.20.30.0/24 127.0.0.0/8 smtpd_relay_restrictions = permit_mynetworks reject_unauth_destination Look Ma! No domain names! Some Postfix versions do the above in smtpd_recipient_restrictions instead of the newer smtpd_relay_restrictions. Wietse
