When I send 20,21 and 23 to my Yahoo account for reference they indicate
attachments but looking at the headers there's just the definition of
the boundary, there's no boundary with an attachment following it.

I think that's a pretty good way of handling it. If you can't make out
what to do with it by following standards then just skip it.

It would be wrong to try to deliver non-compliant mail, especially since
it's probably spam and virus (and Microsoft), it would be better to be
able to block non-compliant mail (or its attachments).
