The MX Record in the host known as the Mail Exchanger (Mail Server) that is responsible for receiving the emails bound for that particular domain. Domains can have multiple MX Records, each normally specifying a different host with a priority level. Hosts with lower priority level are to be contacted first as emails arrive.
