in reply to Modules for PayPal IPN and usage

Doesn't "receiver" mean you? I'm not familiar with PayPal at all, but it sounds like you have to make sure you'd "registered and confimed" your *own* address with them to ensure you get your payment.

I'd suggest asking them, though. First, to make sure you're not losing money. And second, to give them a chance to clean up their docs.
