Topic: iRedOS SMTP Banner Problem
Just installed iRedOS and I am having a problem with the banner. Basically, it's not matching the FQDN I have setup for this machine, it's showing localhost.localdomain instead:
220 localhost.localdomain ESMTP iRedMail
I tried changing the 127.0.0.1 entry in /etc/hosts to that of my FQDN, rebooted, but then for whatever reason I am unable to connect to the SMTP server (postfix). It will attempt to connect and then close the connection.
I also uncommented smtpd_banner = $myhostname ESMTP $mail_name in main.cf and restarted postfix with no change.
I'm sure this is a simple fix, but I can't quite put a finger on it.
