MX

What is an MX record?

A MX (Mail eXchanger) record maps a domain (example.com) to a mail server that is responsible for receiving email for the domain. It tells other “sending” mail servers where they should deliver your email.

Multiple records and priority

Multiple MX records are supported (and recommended) for redundancy and load balancing. A priority value determines which servers should be sent to first. Lower values mean higher priority. e.g. 5 is a higher priority than 10. The priority can also be equal and the servers are round robin load balanced.

Example

Name	Type	Value	Priority
example.com	MX	mail1.tibus.net	5
example.com	MX	mail2.tibus.net	10
