(Speaking as one who has also worked quite a bit on libmime.) And, on top of that, we had only 20 years to fix it. ;-) Seriously: When deleting an attachment, the signature (which is usually just another attachment or MIME part) should be stripped as well, in the same operation. Doesn't need any crypto knowledge. It's the same kind of operation that was done to remove the attachment in the first place.
