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

Also written: DMARC

A mail check, built on SPF and DKIM, that confirms a message really came from the domain it shows. It protects only the exact domain that publishes it, so a lookalike such as kettleandcrane-group.com can pass for itself, and a pass does not prove the sender is genuine.
