Troubleshoot Mail Server Using DigitalOcean Tutorial?
I followed the tutorial https://www.digitalocean.com/community/tutorials/how-to-configure-a-mail-server-using-postfix-dovecot-mysql-and-spamassassin to try and get a mail server running at home. I’m on Comcast, however, who blocks port 25, so I added this into the config in order to use the Comcast relay. This is the only thing I did differently.
relayhost = [smtp.comcast.net]:587 smtp_sasl_auth_enable = yes smtp_sasl_password_maps = hash:/etc/postfix/sasl_passwd smtp_sasl_security_options =
I then made a file /etc/postfix/sasl_passwd and put:
As far as I’m aware, this should work, but when I put in the details in Gmail it says it can’t reach the server. As for Gmail, I have:
SMTP Server: mydomain.net Port: 25 [Since I'm using the relay, I'm assuming my end should be configured to 587 and outside should be pointed to 25, although I did try 587 on Gmail, too, to no avail.] Username: firstname.lastname@example.org [I have 3 test accounts] Password: [That account's password] And I have "Secured connection using TLS" bubbled.
How should I go about troubleshooting this?
