I got a lot futher now.
On my final checkout from Paypal, I am getting this message:
Unable to process payment. Please contact the merchant as the shipping address provided by the merchant is invalid, and the merchant has requested that your order must be shipped to that address.
What does that mean?
Also, I do not see the Univeral Email server behavior on the confirm.php and pp_confirm.php pages. I don't even know how the email is getting sent.
