Paypal Pro with multiple email addy [ conflict with eBay emails ]

I've been using eBay for a long time now...
the Paypal email address we use for eBay is: [email protected]

Now with ZenCart, the email we want to use is: [email protected]

The problem is when someone makes a purchase on our website,
I've been getting receipts to: [email protected]

I think my customers are also getting their order receipt from this same address...
which is an email address that doesn't match the website they just purchased from!!!

I've gone through every PaypalPro setting in the ZC admin AND Paypal admin...
for the life of me, I can't find anywhere to specify which email address is used for website transactions...???

This is bad...
I'd be suspicious if I ordered from AnniesSite.com and got an email receipt from JoesGarage.com?!?!? :unsure:
