Why Should I Set Priority For an MX Record Set?

The priority you set when you add an MX record set specifies the sequence that an email server receives emails. A smaller value indicates a higher priority.

If there is only one MX record set, the priority is not applied.
If there are multiple MX record sets, the DNS server of the email sender preferentially sends emails to the email server with the highest priority.
If the email server becomes faulty, the DNS server automatically sends emails to the email server with the second highest priority.

For details about how to add MX record sets, see Managing Record Sets.
