Internationalized Delivery Status and Disposition Notifications
RFC 6533, “Internationalized Delivery Status and Disposition Notifications”, is a Proposed Standard document published in February 2012 by T. Hansen, C. Newman, A. Melnikov. It updates RFC 3461, RFC 3464, RFC 3798, RFC 6522. It obsoletes RFC 5337. The canonical text is published by the RFC Editor.
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. [STANDARDS-TRACK]
What “Proposed Standard” means
An entry-level standards-track specification: stable, peer-reviewed and a solid basis for implementation, though it may still evolve before becoming an Internet Standard.
