Hi all, I'm currently in trouble with postfix (here my config). When I go here : https://www.checktls.com/TestReceiver I try the port 587 and it's working but when I put 465… get stuck :-( An idea how to solve it ? Thanks Code: seconds test stage and result [000.076] Connected to server [030.090] Read failed (reason: timed out ) [030.091] <-- [030.091] We are not allowed to connect [030.092] --> QUIT [030.167] <-- Code: smtp inet n - y - - smtpd #smtp inet n - y - 1 postscreen #smtpd pass - - y - - smtpd #dnsblog unix - - y - 0 dnsblog #tlsproxy unix - - y - 0 tlsproxy submission inet n - y - - 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=permit_sasl_authenticated,reject # -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 smtps inet n - y - - smtpd -o syslog_name=postfix/smtps -o smtpd_tls_wrappermode=yes -o smtpd_sasl_auth_enable=yes # -o smtpd_reject_unlisted_recipient=no -o smtpd_client_restrictions=permit_sasl_authenticated,reject # -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
