Internet Engineering Task Force (IETF) T. Hansen, Ed. Request for Comments: 6533 AT&T Laboratories Obsoletes: 5337 C. Newman Updates: 3461, 3464, 3798, 6522 Oracle Category: Standards Track A. Melnikov ISSN: 2070-1721 Isode Ltd February 2012 Internationalized Delivery Status and Disposition Notifications Abstract Delivery status notifications (DSNs) are critical to the correct operation of an email system. However, the existing Draft Standards (RFC 3461, RFC 3464, RFC 6522) are presently limited to ASCII text in the machine-readable portions of the protocol. This specification adds a new address type for international email addresses so an original recipient address with non-ASCII characters can be correctly preserved even after downgrading. This also provides updated content return media types for delivery status notifications and message disposition notifications to support use of the new address type. This document extends RFC 3461, RFC 3464, RFC 3798, and RFC 6522. Status of This Memo This is an Internet Standards Track document. This document is a product of the Internet Engineering Task Force (IETF). It represents the consensus of the IETF community. It has received public review and has been approved for publication by the Internet Engineering Steering Group (IESG). Further information on Internet Standards is available in Section 2 of RFC 5741.

Standards Track [Page 2] RFC 6533 Internationalized DSN and MDNs February 2012 1. Introduction When an email message is transmitted using the SMTPUTF8 [RFC6531] extension and Internationalized Email Headers [RFC6532], it is sometimes necessary to return that message or generate a Message Disposition Notification (MDN) [RFC3798]. As a message sent to multiple recipients can generate a status and disposition notification for each recipient, it is helpful if a client can correlate these notifications based on the recipient address itShow full document text
