Support return orders that are unreferenced in Order Management? The customer uploads a bunch of items that need to be returned for credit. And there is no info for the original order.

Fulfill orders for electronic ordering. There is no physical shipment. It's just that once the orders are in, you send an email notification to the customer with the license keys for activating the product. If the email delivery failed, they want the system to notify the failure. Then resend the email till the customer acknowledges the email delivery.
