What Are “mx Records”?

Answer»

MX records specify the mailing server of the DOMAIN. An MX record shows to which computer a mail of a particular domain should be sent. The MX record also includes a priority number, which can be used to DETERMINE several computers where the mail for the domain can be sent. The first attempt is to deliver the mail to the computer with the highest priority (lowest value). If this attempt fails, the mail goes to the next computer (with a HIGHER priority value), and so on.
