Guys, you are right as the IPN script does handle the information and pass it back to Paypal but that's not the issue.

We only get one place to enter the IPN web address in Paypal. I have two stores I want to work on the same account but that means I don't have a place in Paypal to enter in the new store's IPN script address. So that's my problem... how can I have it call a different IPN based on what email address was sent to Paypal?
