Often you will see multiple of these used in a post, so if scoring I'd suggest using a regex, and not use a rule per hit else it might be scored so high as to delete. There are inherit dangers of what you want to do, but if you're the only mail user, then you know and accept the risks, if you host mail for others, under no circumstances should you do any of this with 100% agreement from all mail users.
