DMARC: Domain Message Authentication Reporting & Conformance (for Email) – Domain Message Authentication Reporting & Conformance

"DMARC, which stands for “Domain-based Message Authentication, Reporting & Conformance”, is an email authentication protocol. It builds on the widely deployed SPF and DKIM protocols, adding a reporting function that allows senders and receivers to improve and monitor protection of the domain from fraudulent email.

DMARC - Wikipedia, the free encyclopedia

"DMARC is built on top of two existing mechanisms, Sender Policy Framework (SPF) and  DomainKeys Identified Mail (DKIM). It allows the sender of an email to publish a policy on which mechanism (DKIM, SPF or both) is employed when sending email and how the receiver should deal with failures. Additionally, it provides a reporting mechanism of actions performed under those policies. It thus coordinates the results of DKIM and SPF and specifies under which circumstances the From: header field, which is often visible to end users, should be considered legitimate."
