L2.APEWS.ORG False Positive #2

This is only the second FP that we have seen, and remember folks, we're using the L2.Apews.org balcklist straight "out-of-the-box" by allowing all connections, testing only the connecting IP address, and inserting an X-Header reference for Apews.org listed senders.

The client found this email in his spam folder and it should not have been there. The IP address seems to be Ebay developers website using Rackspace web hosting so maybe Rackspace are listed rather than Ebay!

  1. Checked this today and it is no longer listed which is good news, one less false positive for the Admins to worry about.
