Neil,
Based on our "Requests for Removal" filed over the past 3+ weeks from
ReturnPath, the number of IPs that you are claiming to have had issues with
appears inflated by a factor of nearly 50%.
More importantly, I feel it is irresponsible to oversimplify a cleared listing
as a "false positive" when speaking of *any* IP reputation system.
Barracuda Reputation does not arbitrarily list hosts. Messages have passed
through each host with characteristics indicative of spam. Those listings
would only have been cleared because someone contacted the BRBL team and
requested their clearance - explicitly volunteering /some/ measure of
responsibility for those hosts going forward. _Accepting_ your
possibly-inflated numbers, the 409 IPs otherwise met the criteria for clearing,
so they were cleared. Apparently 22 IPs did not, and those were not cleared.
That those same 431 listings were not found on any other DNSBLs of which you
are aware would be what most people call a feature.
Bob

My point is the 409 false positives. Sorry if I was unclear or obtuse.
