You may have multiple MX records assigned, for example MX10, MX20, and MX30 may also be assigned a mail server.his is a fail-safe measure you can use in the event your default mail server is down.

It also prevents loss of email messages during your main mail server?s downtime. This is called MX Priority. The lowest number MX record is the first one attempted for delivery.

You only need to modify your MX Records if you host a domain and host your email account somewhere else.
