RFC 5248: A Registry for SMTP Enhanced Mail System Status Codes

In plain English — editorial summary, not part of the RFC

The specification for enhanced mail system status codes, RFC 3463, establishes a new code model and lists a collection of status codes. While it anticipated that more codes would be added over time, it did not provide an explicit mechanism for registering and tracking those codes. This document specifies an IANA registry for mail system enhanced status codes, and initializes that registry with the codes so far established in published standards-track documents, as well as other codes that have become established in the industry. This document specifies an Internet Best Current Practices for the Internet Community, and requests discussion and suggestions for improvements.
