Email form?

Ok I’ve followed the tutorial and pretty much copied everything on there to try and get it working first however Im not recieving the emails. The site Im working on is here

Do I need anything other then this in my email.php file?

<?php

$sendTo = "[email protected]";
$subject = "CFL Form Support Submission";

$headers = "From: " . $_POST["name"];
$headers .= "<" . $_POST["email"] . ">
";
$headers .= "Reply-To: " . $_POST["email"]
; 
$headers .= "Return-Path: " . $_POST["email"]; 
$message = $_POST["message"];

mail($sendTo, $subject, $body, $headers);

?>
