Help Needed!!

Hi I'm having problems with a form handler, it only sends the email to hotmail addresses, not aol.

<?php

$emailSubject = 'Online Enquiry';
$webMaster = 'example@example.com';
@extract($_POST);
$name = stripslashes($name);
$phone = stripslashes($phone);
$email = stripslashes($email);
$subject = stripslashes($subject);
$message = stripslashes($message);

//

$date = (date ("F j, Y"));
$time = (date ("H:i:s"));
$IPnumber = getenv("REMOTE_ADDR");

$_POST['phone'] = preg_replace("/[\n\r]+/", "", $_POST['phone']);
$_POST['name'] = preg_replace("/[\n\r]+/", "", $_POST['name']);
$_POST['subject'] = preg_replace("/[\n\r]+/", "", $_POST['subject']);
$_POST['message'] = preg_replace("/[\n\r]+/", "", $_POST['message']);
$_POST['email'] = preg_replace("/[\n\r]+/", "", $_POST['email']);

$body = <<<EOD
<h1>Example Message</h1>
EOD;

$headers = "MIME-Version: 1.0\r\n";
$headers .= "Content-type: text/html; charset=utf-8\r\n";
$headers .= "From: example <example@example.com>\r\n";
$success = mail($webMaster, $emailSubject, $body, $headers);
?>

 

Any errors? I would suggest using PEAR library since the native php mail() function doesn't work that good.
