What type of record does DNS use to find a mail service?

  • Service (SRV) DNS record
  • Canonical (CNAME) DNS record
  • Mail Exchanger (MX) DNS record
  • Host (A) DNS record

Explanation:

A mail exchanger record (MX record) is a type of resource record in the Domain Name System that specifies a mail server responsible for accepting email messages on behalf of a recipient’s domain, and a preference value used to prioritize mail delivery if multiple mail servers are available. The set of MX records of a domain name specifies how email should be routed with the Simple Mail Transfer Protocol (SMTP).
