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.

This document is a product of the Domain-based Message Authentication, Reporting & Conformance Working Group of the IETF.

This is now a Proposed Standard.
