I have installed
postfix following this tutorial but when I try to
telnet mail.mydomain.com 110 (995,993,143 or 25) it throws the following error:
Telnet: Unable to connect to remote host: Connection refused
I looked at this answer of ServerFault but it couldn't help! Any clue how to fix this (or a link to another tutorial), I've been trying to install a servermail on my VPS for a week now, cannot get it to work!
