Is there any work going/gone on/planned to enable exim to report delivery
status notifications using RFC1892 multipart/report MIME messages? At
present it seems to just appends the full headers and body to the
human-readable delivery report (which isn't terribly pleasant if the
message is a large JPEG image ;-). It would be great to have errors
reported in a message/rfc822 attachment.
RFC1892 says:
<snip>
The Multipart/Report content-type contains either two or three sub-
parts, in the following order:
(1) [required] The first body part contains human readable message.
The purpose of this message is to provide an easily-understood
description of the condition(s) that caused the report to be
generated, for a human reader who may not have an user agent
capable of interpreting the second section of the
Multipart/Report.
The text in the first section may be in any MIME standards-track
content-type, charset, or language. Where a description of the
error is desired in several languages or several media, a
Multipart/Alternative construct may be used.
This body part may also be used to send detailed information
that cannot be easily formatted into a Message/Report body part.
(2) [required] A machine parsable body part containing an account
of the reported message handling event. The purpose of this body
part is to provide a machine-readable description of the
condition(s) which caused the report to be generated, along with
details not present in the first body part that may be useful to
human experts. An initial body part, Message/delivery-status is
defined in [DSN]
(3) [optional] A body part containing the returned message or a
portion thereof. This information may be useful to aid human
experts in diagnosing problems. (Although it may also be useful
to allow the sender to identify the message which the report was
issued, it is hoped that the envelope-id and original-recipient-
address returned in the Message/Report body part will replace
the traditional use of the returned content for this purpose.)
