What is an MX record?

Mail Exchanger. This is a mail handler that is used to send Internet mail. You use the MX prefix when sending outgoing mail from a VMS mail system to indicate that the mail is not for a local user, but should be sent out on the Internet.

An MX record must contain a host name defined by an IN A record. In CNAME aliases are not allowed to be used as MX record host names. It also sets priority levels for different services.

MX record changes are often made when mail hosting is to be done seperate from website hosting. This is often the case with personal mail servers and third party webmail programs.

MX records can be easily changed right from our hosting control panel.
