Estimated reading time: 2 minutes

Mail Exchange (MX) records specify the mail server responsible for accepting mail on behalf of the domain. The record is a resource in the Domain Name System (DNS), and it is possible for a single domain to have multiple MX records. Multiple records are largely configured for availability, redundancy, and load balancing reasons.
