Hi Fantomas, It's very kind of you for all the details of your answer. I would like just a bit more information.
1. If I change "smtpd_sasl_auth_enable=yes" in main.cf, Is there any issue with "smtpd_sasl_security_options = noanonymous" ? This option will be apply to submission and smtps in master.cf ? 2. In master.cf, what "-o milter_macro_daemon_name=ORIGINATING" is ? Is it with my postfix 2.5.5 compatible ? Best regards -- Sent from: http://postfix.1071664.n5.nabble.com/Postfix-Users-f2.html
