Definition
An MX (Mail Exchanger) record is a type of DNS record that specifies which mail server is responsible for accepting email on behalf of a domain. When you send an email to user@example.com, your mail server looks up the MX records for example.com to find where to deliver the message. MX records include a priority number, allowing domains to have backup mail servers. Email verification services check MX records to confirm a domain can receive email.
