What is an MX record?

Updated October 18, 2022 13:54

An MX record is a DNS entry that identifies where mail for a domain should go.

For example the MX record for blacknight.ie is av-priv.blacknight.ie

This means that all mail for the blacknight.ie (ie. anything@blacknight.ie) should be sent to the server associated with av-priv.blacknight.ie

An mx record has to be hostname ie. it CANNOT be an IP address.
