The MX record type

The MX (mail exchange) record type contains the name of the mail server responsible for the domain.

Examples #

Here, we query for MX records of the domain “mx-example.lookup.dog”. The result is a record with the mail domain “some.mail.server.” and priority 10.

$ dog MX mx-example.lookup.dog
MX mx-example.lookup.dog. 1h00m00s   10 "some.mail.server."
