This is my code. I spent hours debugging it. I can't see the error. Why didn't I didn't receive the email?
if(isset($_POST['submit'])){
$to = "admin@example.com";
$subject = "Mesej Website";
$from = $_POST['email'];
$headers = "From: " . strip_tags($from) . "\r\n";
$headers .= "Reply-To: ". strip_tags($from) . "\r\n";
$headers .= "MIME-Version: 1.0\r\n";
$headers .= "Content-Type: text/html; charset=ISO-8859-1\r\n";
$message = '<html><body>';
$message .= '<h3>Mesej Daripada '.$_POST['name'].'</h3>';
$message .= '<div style="margin-top:20px;">'.$_POST['message'].'</div>';
$message = '</body></html>';
mail($to,$subject,$message,$headers) or die('mail sending error');
