Not receiving PayPal IPN confirmation emails (sandbox)
I've set up IPN for PayPal payments standard in sandbox mode. My IPN successfully validates in the IPN test environment in PayPal and my payment correctly shows up in the both my testing seller and buyer accounts in PayPal sandbox. However, I'm not receiving any emails from the PayPal sandbox confirming the order to the seller and buyer.
Any ideas as to why this may be?
