DMARC (Domain-based Message Authentication, Reporting, and Conformance)

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 the authentication protocols SPF, DKIM, and DMARC, a domain may be protected from being used in business email compromises, phishing emails, email scams, and other cyber threat activities and the domain owner will gain control over blocking malicious spoofs at receivers and where the spoofs are returned to for security and legal action.
