Maybe the original poster was just after something like:
If the attachment is on the list of disallowed file types, remove the
current extension (e.g. .avi) and replace it with .txt, which the recipient
could easily change later once they are sure the attachment is safe. Seems
to me like this could be done pretty easily and would be a middle of the
road for people not wanting to totally block the attachment but at least
prevent the "click and execute" danger.
