Email Authentication Status Codes
RFC 7372, “Email Authentication Status Codes”, is a Proposed Standard document published in September 2014 by M. Kucherawy. It updates RFC 7208. The canonical text is published by the RFC Editor.
Abstract
This document registers code points to allow status codes to be returned to an email client to indicate that a message is being rejected or deferred specifically because of email authentication failures.
This document updates RFC 7208, since some of the code points registered replace the ones recommended for use in that document.
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 7372 is hosted at rfc-editor.org. Available in TXT,HTML.
