RFC 3463 Draft Standard Transport

Enhanced Mail System Status Codes

This document defines a set of extended status codes for use within the mail system for delivery status reports, tracking, and improved diagnostics. In combination with other information provided in the Delivery Status Notification (DSN) delivery report, these codes facilitate media and language independent rendering of message delivery status. [STANDARDS-TRACK]

Status
Draft Standard. A maturity level the IETF retired in 2011. Documents that had reached it kept the label, so it still appears on current work such as RFC 5321.
