SMTP Setup?

[Me.B]

I have everything installed on CentOS 6.5 and its all works fine. I've opened up all the ports I need for the servers. I can send and receive mail using webmail without any issues. I have made an A record for smtp, mail, and pop3. I'm not really sure where to go from here.

You should create

mail.domain.com A record toward server IP
domain.com MX mail.domain.com
if you would like to have shortcuts you can create:
pop.domain.com cname mail.domaine.com

It's easy to configure outlook.
