# What is an MX record?

## DNS MX Record 

MX stands for *Mail Exchange Record* or mail exchange record. This is a [DNS](https://help.ex2.com/en/article/what-is-the-domain-name-system-or-dns-oen40o/?bust=1784819338957) record that works a bit like a phone book.

An MX record includes a name, an associated IP address and a record of the parameters associated with the DNS where the mail server is located. It tells the sending server where to send email messages. Thus, communication between users active on the network is enabled easily. 

Most MX records include the MX record priority setting, the domain to which the MX record points, the hosting record, and the TTL (lifetime).
