It seems paypal has changed the IPN system. Now for every recurring payment, a notice is sent on every payment made to the IPN system. This means any old urls still having recurring payments or new ones will need to handle this differently.


For the old urls, a success code is needed to be sent to paypal upon receipt of the IPN, for new IPNs being processed on live IPN links, the system will now need to check the status of the order, and then send emails based on the status that are more clear to the customer.
