Domain-Based Message Authentication, Reporting, and Conformance Aggregate Reporting
RFC 9990, “Domain-Based Message Authentication, Reporting, and Conformance Aggregate Reporting”, is a Proposed Standard document published in May 2026 by A. Brotman. It obsoletes RFC 7489. The canonical text is published by the RFC Editor.
Abstract
Domain-based Message Authentication, Reporting, and Conformance (DMARC) allows for Domain Owners to request aggregate reports from receivers. This report is an XML document and contains extensible elements that allow for other types of data to be specified later. The aggregate reports can be submitted by the receiver to the Domain Owner's specified destination as declared in the associated DNS record.
This document obsoletes RFC 7489.
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.
The canonical text of RFC 9990 is hosted at rfc-editor.org. Available in HTML,TXT,PDF,XML.
