CNAME Setup on Different Server

view story

http://serverfault.com – I have domain and hosting at GoDaddy.com with domain earthline.info. But my email is located at CBN.net.id. I have setup the mx with this configuration: But for CNAME, i'm not sure what i must setup for the mail, imap, smtp and etc. I'm not sure because in my outlook, incoming and outgoing server i use mail.earthline.info. Did it will make sure the mail will go through CBN.net.id server? (HowTos)
