Abstract
Domain-based Message Authentication, Reporting, and Conformance (DMARC) is a mechanism by which a Domain Owner can request feedback about email messages using their domain in the From: address field. This document describes "failure reports", or "failed message reports", which provide details about individual messages that failed to authenticate according to the DMARC mechanism. This document updates RFC 6591 and obsoletes RFC 7489.
