Question

I am having trouble with Paypal IPN About one thing,

As I understood, paypal redirects the user to a page of us after the successful order, then calls our IPN page, after the transection with post variables including result.

Paypal sends the mail of the order owner in the post variables, but what if the mail in the site and paypal are different.

If PayPal is calling the ipn page, sessions won’t work. If i don’t check the mail, I won’t be able to catch simultaneously IPN orders ( I think ).

I saw something about txn_id and receipt_id, but if I’am not sending the variables, how can they help me to catch the user.

I am Mixed a bit.

Thanks for any reply.
Regards.
