How DMARC works

DMARC stands for Domain-based Message Authentication, Reporting & Conformance. It is an email authorization protocol that is built upon already existing protocols, such as Sender Policy Framework (SPF) and DomainKeys Identified Message (DKIM).

If the email passes the authentication, it will be delivered and can be trusted. If the email fails the check, depending on the instructions held within the DMARC record the email could be delivered, quarantined or rejected.
