MX record

A Mail Exchange (MX) record describes how an email should be relayed and routed to the end user. It’s also called a Domain Name System MX record, or DNS MX record, because it directs email from a domain to a server via the Simple Mail Transfer Protocol (SMTP). This ensures the email is relayed from the sender to the receiver.
