Another method for filtering after the submit might look like the following. Be sure to change $_POST to $_GET if you are using that method.

foreach( $_POST as $value ){
  if( stripos($value,'Content-Type:') !== FALSE ){
    mail('[email protected]','Spammer Bot Attempt',$_SERVER['REMOTE_ADDR']);
     exit("{$_SERVER['REMOTE_ADDR']} Has been Recorded");
  }
}
