I've been using Form mailer for a couple years but now have a huge issue with SPAMMERS...

Here is my Formmail code it is located at the top of the PHP file

Code:
<form method="post" action="http://nasf.net/cgi-bin/form1.php" name="NASF Forms ">
    <input type="hidden" name="recipients" value="webmaster@nasf.net" />
    <input type="hidden"
...
