[exim] Automated Abuse Reports

I've started sending out automated abuse reports for spam and viruses
and one person pointed out that there is a standard being developed for
automated abuse.

I'm still wondering what I would have to do to turn a message into an
attachment and create attachments that would comply with this spec. A
few days ago I asked about the ability of Exim to create attachments and
no one had an answer. Should I assume that Exim can't yet do this? If
not then it would be a good feature to add.
