Hello all - My ISP has started blocking port 25 and I am having difficulty adding port 587 to my postfix configuration. I have added the following: 1) TLS settings in /etc/postfix/main.cf smtpd_tls_cert_file = /etc/postfix/smtpd.cert smtpd_tls_key_file = /etc/postfix/smtpd.key smtpd_use_tls = yes smtpd_tls_session_cache_database = btree:${data_directory}/smtpd_scache smtp_tls_session_cache_database = btree:${data_directory}/smtp_scache smtp_tls_security_level = encrypt smtp_tls_CAfile = /etc/ssl/certs/ca-certificates.crt smtp_tls_session_cache_database = btree:/var/lib/postfix/smtpd_scache_tls tls_random_source=dev:/dev/urandom 2) SASL settings in /etc/postfix/main.cf smtp_sasl_auth_enable = yes smtp_sasl_security_options = noanonymous smtp_sasl_password_maps = hash:/etc/postfix/saslpasswd smtp_always_send_ehlo = yes broken_sasl_auth_clients = yes smtpd_sasl_authenticated_header = yes 3) relayhost settings in /etc/postfix/main.cf relayhost = [smtp.comcast.net]:587 4) /etc/postfix/saslpasswd [smtp.comcast.net]:587 <MyUser>:<MyPasswd> 5) I hashed /etc/postfix/saslpasswd with the following command: postmap /etc/postfix/saslpasswd 6) I then executed the following commands: postfix reload /etc/init.d/postfix restart 7) I opened port 587 on my router 8) I added port 587 to my ISPConfig3 firewall I still cannot send or receive emails, but I'm seeing this in my mail log: postfix/smtp[4210]: 341721120004: to=, relay=127.0.0.1[127.0.0.1]:10024, delay=1039, delays=1039/0.04/0.01/0, dsn=4.7.4, status=deferred (TLS is required, but was not offered by host 127.0.0.1[127.0.0.1]) Is anything in configuration incorrect ? Am I missing any steps ? Thanks !
you need port 25 also because mail serveres from arround de world will try to send you e-mail to that port not 587
Hi Titex (et all) - I indeed have port 25 open, as well as 587. I forgot to display the smtpd lines from my master.cf file. I believe they are: smtp inet n - - - - smtpd 587 inet n - - - - smtpd submission inet n - - - - smtpd Please note the 3rd column of "-/n" is "-". Also, my Mail Queue has 3 messages waiting, with the following error: (TLS is required, but was not offered by host 127.0.0.1[127.0.0.1]) Nothing coming in or going out ... Thanks !
