"Internationalized Delivery Status and Disposition Notifications", Chris Newman, Alexey Melnikov, 13-Jul-09. ( bytes)

Delivery status notifications (DSNs) are critical to the correct operation of an email system. However, the existing Draft Standards (RFC 3461, RFC 3462, RFC 3464) are presently limited to US-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-US-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 experimentally extends RFC 3461, RFC 3464, and RFC 3798.

"Guidelines for Internationalized Email Clients", Ernie Dainow, Kazunori Fujiwara, 10-Jul-09. ( bytes)

This document provides some guidelines for email clients that support Email Address Internationalization (EAI) as outlined in RFC 4952. A number of interoperability cases between different versions of email components are reviewed. Recommendations are made to improve interoperability and usability and to minimize discrepancies between the display of composed and received email in different language environments.
