Beneath considering how the message should look like that a
novice understands it best, the existing (proposed?) standart
"Delivery status notification" (DSN) as described by RFC 1891
should be kept in mind.
I don't know if this is the actual definition, but those DSNs look
a bit different than the current messages.
They seem to consist of MIME-messages with three parts:
- a "user explaining" part that is targeted at the (probably
novice) reader
- a "message/delivery-status"-typed part with a formal syntax
which mail to whom failed why
- a citation-part (headers/message).
If a nice guy should implement a new interface for responses,
it might be great to take care of this aspect.
sendmail produces conforming error messages in its current
versions, and you might have already seen the one or the other.
In RFC1891 one example for such a DSN is given, that I attach
below.
