I got an email this morning from paypal - and yes, I've done checks to ensure that is 100% paypal.
Has anyone got a message like this? Is there really anything that needs to be done, since it seems to be working fine.
Please check your server that handles PayPal Instant Payment Notifications (IPN). Instant Payment Notifications sent to the following URL(s) are failing:
http://XXXXXXXXXX:81//user?payment=payp ... 77&subid=1
If you do not recognize this URL, you may be using a service provider that is using IPN on your behalf. Please contact your service provider with the above information. If this problem continues, IPNs may be disabled for your account.
Thank you for your prompt attention to this issue.
