Domain-Based Message Authentication, Reporting, and Conformance
RFC 9989, “Domain-Based Message Authentication, Reporting, and Conformance”, is a Proposed Standard document published in May 2026 by T. Herr, J. Levine. It obsoletes RFC 7489, RFC 9091. The canonical text is published by the RFC Editor.
Abstract
This document describes the Domain-based Message Authentication, Reporting, and Conformance (DMARC) protocol.
DMARC permits the owner of an email's Author Domain to enable validation of the domain's use to indicate the Domain Owner's or Public Suffix Operator's message handling preference regarding failed validation and to request reports about the use of the domain name. Mail-receiving organizations can use this information when evaluating handling choices for incoming mail.
This document obsoletes RFCs 7489 and 9091.
What “Proposed Standard” means
An entry-level standards-track specification: stable, peer-reviewed and a solid basis for implementation, though it may still evolve before becoming an Internet Standard.
