I am trying to send an Instant Payment Notification (IPN) to my server using Instant Payment Notification (IPN) simulator on Paypal Developer site.
I have been searching all over the internet and I found a site which allows to test the ipn http://samples.geekality.net/ipn/
when I use this url http://samples.geekality.net/ipn/listener.php in IPN simulator it shows me the data on this sample site but when I use my own site's url which is something like this http://example.com/appointments/payment/notify it just doesn't work I am sending an mail function using to my email something like this:
mail('email@example.com', 'notify action performed', http_build_query($_REQUEST));
I've just tried to reproduce your issue, but everything seems to work fine. Maybe the email was sent in the spam folder, or maybe you're server is having problems with the
