uggh, been there done that... The issue is fundamental to the way the script works, so I don't know if there is really a good way to patch this one up *and* retain backwards compatability.

However, when I inherited a similiar situation, I did manage to stop the script kiddies. Luckilly the entire site was dynamic (SSI), so we put an extra field in all the FORM pages. This value of this hidden field changed every hour and was valid for two hours. If a request came in that didn't have a valid value, we didn't send the mail.

We managed to get rid of the real-world problem, even though theoretically it wasn't any more secure. It does require slight modification to the submission page, so it might not be what you need, but it did work fine for us.
