Implementing Domain-based Message Authentication, Reporting, and Conformance (DMARC) provides critical email security benefits by protecting domain names from spoofing, phishing scams, and fraudulent business email compromise attacks. DMARC leverages existing Sender Policy Framework and DomainKeys Identified Mail protocols to give domain owners control over how receiving mail servers handle unauthorized messages, while providing comprehensive XML reporting data that offers visibility into incoming email traffic and threat vectors targeting corporate communications.
