testing php's mail function

mailTest.php

<?php
# http://learn.koding.com/guides/enable-php-mail-function/
$to      = '[email protected]';
$subject = 'the subject';
$message = 'hello';
$headers = 'From: [email protected]' . "\r\n" .
    'Reply-To: [email protected]' . "\r\n" .
    'X-Mailer: PHP/' . phpversion();

mail($to, $subject, $message, $headers);

echo "Mail sent";

Hi, I had tried the same without the $headers. It worked fine. I will have to check with a custom head and try further.
