I have a VPS with cpanel and I'm attempting to setup my own SMTP server so that I can use smtp.mydomain.com.
I've looked at a server in which this is already setup, and if I go into WHM > View Relayers I can see the domain name is entered there, while when I look at my new box, it only has the username 'root'.
What do I need to look at? Where is this configuration setup?
I've heard that SMTP is on by default with cpanel, so is this just a matter of setting up an A NAME record or something like this with the DNS?
Any help would be greatly appreciated.
