Frequently Asked Questions

What does an MX priority value mean?

A lower preference value has higher priority. Sending mail servers normally try the lowest-value available exchanger first.

Can multiple MX records have the same priority?

Yes. Mail servers may choose between exchangers with equal preference, which can distribute delivery across multiple hosts.

Does an MX record prove that email is working?

No. MX records show where mail should be delivered. They do not confirm that the server accepts mail, that a mailbox exists, or that delivery will succeed.
