                    Email Authentication Status Codes

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.
