Document: draft-ietf-appsawg-email-auth-codes-04 Reviewer: Peter Yee Review Date: July-31-2014 IETF LC End Date: August-1-2014 IESG Telechat date: August-7-2014 Summary: This draft is ready for publication as a Standards Track RFC. [Ready] This draft species additional SMTP enhanced mail system status codes to provide indications for email authentication failures. The merest nit I could find is that some references in the document are not indicated by square brackets, but I can't tell if that's just an artifact from the markup conversion tool because these non-bracketed references only appear in tables.
