// Revision Notes
// 11/04/11 - changed post back url from https://www.paypal.com/cgi-bin/webscr to https://ipnpb.paypal.com/cgi-bin/webscr
// For more info see below:
// https://www.x.com/content/bulletin-ip-address-expansion-paypal-services
// "ACTION REQUIRED: if you are using IPN (Instant Payment Notification) for Order Management and your IPN listener script is behind a firewall that uses ACL (Access Control List) rules which restrict outbound traffic to a limited number of IP addresses, then you may need to do one of the following:
// To continue posting back to https://www.paypal.com to perform IPN validation you will need to update your firewall ACL to allow outbound access to *any* IP address for the servers that host your IPN script
// OR Alternatively, you will need to modify your IPN script to post back IPNs to the newly created URL https://ipnpb.paypal.com using HTTPS (port 443) and update firewall ACL rules to allow outbound access to the ipnpb.paypal.com IP ranges (see end of message)."
