Thanks in advance.'PayPalIpnUrl' => 'www.sandbox.paypal.com', // The URL for PayPal's IPN responses (www.paypal.com for live and www.sandbox.paypal.com for testing)
'PayPalBusinessEmail' => 'admin@localhost', // Enter the e-mail under which you have registered your business account.
'PayPalReceiverEmails' => array( // These are the receiver e-mail addresses who are allowed to receive payment.
//'admin2@localhost', // -- This array may be empty if you only use one e-mail
//'admin3@localhost' // -- because your Business Email is also checked.
