MX Record
A DNS record that names the mail servers responsible for receiving email for a domain.
Definition
An MX (Mail Exchange) record is a DNS entry that tells senders which servers accept email for a domain, and in what priority order. Email verification uses MX lookups to confirm a domain is configured to receive mail at all; a domain with no MX record cannot accept email, so any address on it is invalid. MX records are the first technical gate before an SMTP check.
