Question 9

Which type of DNS record is used to specify the mail server responsible for accepting email messages on behalf of a recipient’s domain?

Answer

3. MX record (A DNS Mail Exchange (MX) record directs a domain’s incoming email to the correct mail server, serving as a critical address label for SMTP routing.
