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.
