What is an MX record?

An MX (Mail Exchange) record is a DNS entry that tells the internet which mail servers are responsible for accepting email on behalf of a domain, and in what order of preference (lower priority number = tried first). Without one, a domain simply cannot receive email — this is different from SPF, DKIM, or DMARC, which govern how outgoing mail is authenticated.
