I download a free script i found to do a paypal transaction for me and script should send the buyer a temporary password to enter the download page with. The only problem I am having is when i run the script through sandbox it is not sending me the email with the login information.
//ipn.php
<?php
include('settings.php');

$paypal_ipn_url = "www.paypal.com";
}
$script_uri = 'http://'.$SERVER['HTTP_HOST'].$SERVER['PHP_SELF'];
// -- GENERATING THE PAYPAL ORDER BUTTON -- //
if ($SERVER['QUERY_STRING'] == 'buy')
{
$thankyou_page_url = str_replace($this_file, 'page.php?thankyou', $script_uri);
