VirtueMart Version 2.0.18a
Joomla Version 2.5.9

This is a pretty fresh install and setup only been working on the site a few days. Today I have received 20+ emails that are as follows:

Subject Line "PayPal IPN Transaction on your site: Possible fraud"

Body of Text:

Error code 506. Possible fraud. Error with REMOTE IP ADDRESS = 66.211.170.66.
The remote address of the script posting to this notify script does not match a valid PayPal ip address

These are the valid IP Addresses: 23.47.98.234,173.0.81.1,173.0.81.33The Order ID received was: e84a08


I am not sure what causes this or what this is from? Anyone seen this before?
