MX Records

An MX record controls which mail server deals with the email sent to your domain and hostnames. With access to the MX record for your domain you can ensure email is routed to a mail server you are running or the mail server of another company providing this service to you.

What are priority levels?

You can include the hostnames of multiple mail servers and assign different priority levels for each one, allowing you to set primary and backup mail servers. The hostname with the lowest priority will be used first. If the mail server with the highest priority fails for any reason, the server with the next highest priority is tried next.
