Need IT: Confirm Attachment Dialogue in E-mail App

Problem: Sending an e-mail in which you confidently announce and describe the contents of an attached file, only to discover after several replies that you *forgot* to attach the file. This happens to me all the time, on both sides of the send/receive equation.

Bill Needs: Nothing all that new...just a little process that kicks off when the user pushes "send" that scans the body of the message looking for variations of the word "attach" (e.g. attached, attachment). It should ignore any text marked as part of a forward or reply, only scanning text entered fresh by the user for the current message.

If an instance of the word "attach" or a derivative is found, the next step is to check to see if there is, indeed, an attachment associated with the message. If there is, do nothing. If there is not, throw a confirm dialogue that says something like

"Hey, did somebody say ? I don't see an attachment with this e-mail. Do you want to:

Button: Send it Anyway, it's just an expression (confirm)
Button: Hold up! I meant to attach this file... (cancel send, bring up browse...dialogue)

Should be easy enough to do. Could be demo'ed with a script, I imagine, but it should be built in to mail handler apps.

Does this Exist? By all means, reply and let me know!
