The MX record is the mail server that handles the mail for the domain (@domain.com).
I usually setup a mailhost.domain.com reference to the IP address of the mail
server the has the user names for the domain. Then I put mailhost.domain.com
into the MX record. The MX record should only reference the mail server's IP
address.
Attached is a sample DNS file.
