Abstract
This document defines an additional set of extended status codes based
on new messaging applications and associated error states since the
creation of the original RFC 1893 document. These include extended
media conversion codes for fax and voice messaging and results for
message tracking.

1. Overview
VPIM and iFAX have identified additional, interesting error cases
important to enumerate. Operational experience has also suggested
additional codes useful to diagnose messaging system failures.
2. New Status Codes
Here they are.
2.1 Network and Routing Status
Keith Moore thought this might be a good addition.
X.4.8 Misrouted message
A message was improperly routed to this MTA or gateway.
This may have happened, for instance, because an MX
record for the recipient's domain inappropriately
directed traffic to the MTA, or because another MTA was
inappropriately (and explicitly) configured to direct
traffic for this recipient to the MTA reporting the
error.
It can also indicate a failure to properly configure the
reporting MTA, when the MTA administrator intended that
the MTA would accept traffic for recipients in that
domain.

2.2 Media Gateway Encodings
Experience with media translating gateways has demonstrated a need for
a richer set of error codes. These codes provide additional detail
useful to enable an end-user to re-compose and resend a message more
likely to succeed.
X.6.6 Fax media not supported
Fax media is not supported by either the delivery
protocol or the next system in the forwarding path. This
error in a successful DSN indicates the message was
delivered without the offending content.
X.6.7 Fax encoding not supported
While fax media is supported, the specific fax encoding
sent is not supported. This error in a successful DSN
indicates the message was delivered without the offending
content.
X.6.8 Voice media not supported
Voice media is not supported by either the delivery
protocol or the next system in the forwarding path. This
error in a successful DSN indicates the message was
delivered without the offending content.
X.6.9 Voice encoding not supported
While voice media is supported, the specific audio
encoding sent is not supported. This error in a
successful DSN indicates the message was delivered
without the offending content.
X.6.10 Text not supported
Text media is not supported by either the delivery
protocol or the next system in the forwarding path. This
error in a successful DSN indicates the message was
delivered without the offending content.
X.6.11 Text Character set not supported
While Text media is supported, the specific character set
or other encoding is not supported. This error in a
successful DSN indicates the message was delivered
without the offending content.

X.6.12 Attachment type not supported
The attachment is not supported by either the delivery
protocol or the next system in the forwarding path. An
attachment is a content with a content-disposition of
`
the message was delivered without the offending content.
X.6.13 Attachment too large
The attachment is too large for the recipient mail system
or protocol. This error in a successful DSN indicates
the message was delivered without the offending content.

4. Security Considerations
This document describes additional status codes to describe failure
conditions with increased precision. Use of these status codes may
disclose additional information about how an internal mail system is
implemented and it's capabilities beyond that currently available.
