It looks like some form of CAPTCHA is the best answer (using an image,
or text questions). This is not an important contact form, so for now,
I'm just going to kill messages with <a href or http:// in them.
Is there a way to make a bot believe that the sending of the email has
failed? Seems like that would be a deterrent if the spammer sees it is
not working. Should I serve a server error? Can you do that with header()?
