DMARC

DMARC (aka Domain-based Message Authentication, Reporting, and Conformance) is an email authentication protocol designed to give email domain owners the ability to protect their domain from unauthorized use, commonly known as email spoofing. By using both authentications methodologies SPF and DKIM, DMARC protects a domain from being used in business email compromise attacks, phishing emails, email scams, and other cyber threat activities.
