All messages with attachments are multipart (unless it's uuencoded, but
that's another whole kettle of fish).

As an example: a typical message with attachment will be
multipart/related.

The multipart/related body will have two parts - multipart/alternative
and the attachment.

The multipart/alternative body  will have two parts - text/plain and
text/html.

Mimedefang will call filter_multipart for the multipart/related and the
multipart/alternative, and will call filter for the text/plain,
text/html and the attachment.

You need to test in filter to see if this is an "attachment", and then
call action_defang.
