Hey, working on my mailserver.
Cannot get it to talk, at all.
1.Talked to my ISP, port 25 has been unblocked on their end.
Looking at my Firewall, it is has rules in place to accept SMTP.
In the Postfix master.cf "smtp inet n - n - - smtpd" is active
But at the end of the day, port scans read it as closed, and It cant read anything from within. What step am I missing here? Ive read tutorial after tutorial, and i got nothing.
