MX record
From Wiki @ Karl Jones dot com
A mail exchanger record (MX record) is a type of resource record in the Domain Name System that specifies a mail server responsible for accepting email messages on behalf of a recipient's domain, and a preference value used to prioritize mail delivery if multiple mail servers are available.
The set of MX records of a domain name specifies how email should be routed with the Simple Mail Transfer Protocol (SMTP).
