Dropping all submissions with "http://" will eliminate a good amount of 
spam, however you will end up with thousands of robot submitted messages 
which contain nonsense messages. I'm not sure how anyone benefits from 
this, but I see it a lot.
Ultimately, you will probably resort to putting a captcha on the form.
See http://www.onlamp.com/pub/a/php/2005/03/31/text_captcha.html for 
examples.
