You mistake is overriding "smtpd_client_restrictions", you should override "smtpd_recipient_restrictions", which is where anti-relay control is implemented in Postfix. Also you SHOULD NOT include 'permit_auth_destination' on the submission port. Whether amavis is appropriate for submission is your call (I see you've disabled header and body checks). -o smtpd_client_restrictions= -o smtpd_helo_restrictions= -o smtpd_sender_restrictions= -o smtpd_recipient_restrictions=permit_mynetworks,permit_sasl_authenticated,reject -o smtpd_data_restrictions= -o smtpd_end_of_data_restrictions= # Uncomment For Postfix 2.10 or later # -o smtpd_relay_restrictions= The stock master.cf file distributed with Postfix source contains: #submission inet n - n - - smtpd # -o syslog_name=postfix/submission # -o smtpd_tls_security_level=encrypt # -o smtpd_sasl_auth_enable=yes # -o smtpd_reject_unlisted_recipient=no # -o smtpd_client_restrictions=$mua_client_restrictions # -o smtpd_helo_restrictions=$mua_helo_restrictions # -o smtpd_sender_restrictions=$mua_sender_restrictions # -o smtpd_recipient_restrictions= # -o smtpd_relay_restrictions=permit_sasl_authenticated,reject # -o milter_macro_daemon_name=ORIGINATING That's usually the best starting point for further customization. Note that this uses indirection via "mua_*_restrictions" to leave the actual definitions up to main.cf, and should perhaps do likewise for "data" and "end_of_data" restrictions. Because this is taken from Postfix 3.1 (snapshot) it uses "relay" rather than "recipient" restrictions. You might find similar commented-out content in $daemon_directory/master.cf for your Postfix version. -- Viktor.
