Domain-based Message Authentication, Reporting and Conformance (DMARC) is an email authentication protocol. It is designed to give email domain owners the ability to protect their domain from unauthorized use, commonly known as email spoofing .
DMARC provides the ability for an organisation to publish a policy that specifies which mechanism (DKIM, SPF, or both) is employed when sending email from that domain; how to check the From: field presented to end users; how the receiver should deal with failures—and a reporting mechanism for actions performed under those policies.
