Explanation
MX (Mail Exchanger) records specify which mail servers are responsible for accepting email on behalf of a domain, along with priority values when multiple servers exist. When an administrator needs to redirect email flow-such as pointing to a new mail server or a third-party email service-they update the domain's MX records. TXT records store arbitrary text (used for verification and policies). SPF is a type of TXT record that defines authorized sending servers for anti-spoofing, but it does not redirect mail flow. CNAME records create aliases for hostnames but are not used to direct email delivery.
