Thanks, Mark. I guess what had me confused is the call to
filter_bad_filename inside filter_multipart in the stock
mimedefang_filter. I don't understand why that would be there. If you
have something with a bad filename, it would seem to me you might want
to action_defang the thing, but you can't do that inside filter_multipart.
