Difficulties switching to port 587 in Postfix
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.cert2) SASL settings in /etc/postfix/main.cf
smtp_sasl_auth_enable = yes3) relayhost settings in /etc/postfix/main.cf
relayhost = [smtp.comcast.net]:5874) /etc/postfix/saslpasswd
[smtp.comcast.net]:587 <MyUser>:<MyPasswd>5) I hashed /etc/postfix/saslpasswd with the following command:
postmap /etc/postfix/saslpasswd6) I then executed the following commands:
postfix reload7) 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: 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 ?
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 - - - - smtpdPlease 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 ... :(
