Abstract

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 it provided; thus, preservation of the original recipient is important. This specification describes how to preserve the original recipient and updates the MDN and DSN formats to support the new address types.

     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.
