Çözüldü Envato hazır sitede email gönderme çalışmıyor

Envato'dan hazır web site aldım fakat iletişim formunu çalıştıramadım. Yardımıcı olabilir misiniz?

[CODE lang="php" title="contact.php"]<?php
/*
* CONFIGURE EVERYTHING HERE
*/

// an email address that will be in the From field of the email.

// subject of the email
$subject = 'New message from contact form';

// form field names and their translations.
// array variable name => Text to appear in the email
$fields = array('InputName' => 'Name', 'email' => 'InputEmail', 'InputMessage' => 'Message');

// message that will be displayed when everything is OK
$okMessage = 'Your message successfully submitted. Thank you, I will get back to you soon!';

// If something goes wrong, we will display this message.
$errorMessage = 'There was an error while submitting the form. Please try again later';

/*
* LET'S DO THE SENDING
*/

// if you are not debugging and don't need error reporting, turn this off by error_reporting(0);
error_reporting(E_ALL & ~E_NOTICE);

try

foreach ($_POST as $key => $value) {
// If the field exists in the $fields array, include it in the email
if (isset($fields[$key])) {
$emailText .= "$fields[$key]: $value\n";
}
}

// All the neccessary headers for the email.
$headers = array('Content-Type: text/plain; charset="UTF-8";',

'Reply-To: ' . $from,
'Return-Path: ' . $from,
);

mail($sendTo, $subject, $emailText, implode("\n", $headers));
