Hello all, I've got Postfix 3.1.3 running on FreeBSD 10.3-STABLE (last updated 1/2/17) at home, where my ISP blocks port 25, so I'm trying to go through Mailjet's SMTP relay. All the required settings as directed by Mailjet's online support are in place for sending on port 587 but Postfix is not even trying to send on port 587, as my /var/log/maillog regularly shows messages like this with every mail attempt: [...] status=deferred (delivery temporarily suspended: connect to smtp-ovhfr11.mailjet.com[5.196.43.135]:25: Operation timed out)
My question: What part of my configuration is telling it not to send on port 587? Any help is appreciated. Thanks, Steve Below is a snippet of my main.cf: ********** # TLS smtpd_use_tls = yes smtpd_tls_security_level = may smtpd_tls_auth_only = yes smtpd_tls_key_file = /usr/local/etc/postfix/myserver.key smtpd_tls_cert_file = /usr/local/etc/postfix/server.crt smtpd_tls_loglevel = 1 smtpd_tls_received_header = yes smtpd_tls_session_cache_timeout = 3600s tls_random_source = dev:/dev/urandom smtpd_tls_ask_ccert= = yes # SASL smtpd_sasl_type = dovecot broken_sasl_auth_clients = yes smtpd_sasl_path = private/auth smtpd_sasl_auth_enable = yes smtpd_sasl_security_options = noanonymous smtpd_recipient_restrictions = permit_sasl_authenticated, permit_mynetworks, reject_unauth_destination smtpd_relay_restrictions = permit_sasl_authenticated, permit_mynetworks, reject_unauth_destination # Forward all SMTP to Mailjet relayhost = [in-v3.mailjet.com]:587 smtp_sender_dependent_authentication = yes sender_dependent_relayhost_maps = hash:/usr/local/etc/postfix/sender_relay smtp_sasl_auth_enable = yes smtp_sasl_security_options = noanonymous smtp_sasl_password_maps = hash:/usr/local/etc/postfix/sasl-passwords ********** And here is a snippet of my master.cf: ********** smtp inet n - n - - smtpd #smtp inet n - n - 1 postscreen #smtpd pass - - n - - smtpd #dnsblog unix - - n - 0 dnsblog #tlsproxy unix - - n - 0 tlsproxy submission inet n - n - - smtpd -o syslog_name=postfix/submission -o smtpd_enforce_tls=yes -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=$mua_sender_restrictions -o smtpd_recipient_restrictions=permit_sasl_authenticated,reject # -o smtpd_relay_restrictions=permit_sasl_authenticated,reject -o milter_macro_daemon_name=ORIGINATING #smtps inet n - n - - smtpd # -o syslog_name=postfix/smtps # -o smtpd_tls_wrappermode=yes # -o smtpd_sasl_auth_enable=yes # -o smtpd_reject_unlisted_recipient=no # -o smtpd_client_restrictions=$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
