Yes... in a way, but I can see you still don't really understand.
1) Create a new blank page to act as your IPN page
2) Update your paypal profile to tell it to use that page as the IPN page
3) Apply the server behavior ->eCart -> Add to cart -> Add from form and use the trigger "successful paypal transaction" and the form "Paypal IPN"
That page will never be displayed but can have functionality like email and database inserts. Search this forum for others implementing IPN we have some rather long threads describing the intricate details.
