Dmarc And Email Security

DMARC, or Domain-based Message Authentication, Reporting & Conformance, is a critical component of email security that helps protect your domain from spoofing and phishing attacks. It works by verifying the sender's identity and ensuring that emails sent from your domain are legitimate.
