SPF vs DMARC

SPF authorizes sending infrastructure. DMARC builds on SPF and DKIM by adding alignment rules and policy instructions.

SPF

SPF tells receivers which systems are allowed to send for a domain, but it does not by itself provide full policy control over spoofing outcomes.

DMARC lets a domain owner publish a policy such as none, quarantine, or reject and can request reporting from receivers.

SPF is useful, but DMARC is what helps turn email authentication into an enforceable policy framework.

SPF Checker Review which servers are authorized to send mail for the domain. DMARC Checker Inspect policy enforcement, alignment, and reporting settings. TXT Lookup Verify the raw TXT records where SPF and DMARC data are published. MX Lookup Confirm delivery targets while reviewing broader email posture.

SPF vs DKIM vs DMARC See how SPF and DMARC fit into the full authentication stack. DKIM vs DMARC Compare message signing and policy enforcement. MX Record vs SPF Record Separate mail-routing records from sender-authorization records.
