That's the way it should look like:

Code:
<?
$to = '[email protected]';
$name = $_REQUEST['name'];
$message = $_REQUEST['message'];
$email = $_REQUEST['email'];
   $msg = "Message From: Online client $email\n\n";
   $msg .= "$name\n\n";
   $msg .= "$message\n\n";
  mail($to, $subject, $msg, "Reply-To: $email");
?>
Things you should consider once it is working: the email should be checked to NOT contain unwanted characters such as newlines
