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.
For the definition of Status, see RFC 2026.
For the definition of Stream, see RFC 8729.
