In recent weeks our spam appliance has flagged an increasing number of previously legit IP's as spam. We are talking fortune 500 companies, even fortune 100 and I know they are not spamming, but when looking them up ALL of them are reported as listed by backscatter or uceprotect networks (level 2 and 3, not level 1).

It's to the point that keeping up the whitelist has been problematic and I have removed those 2 from our spam database search on the appliance. Anyone else use these blacklist providers and having recent issues? Up until 2 weeks ago, we had not changed our DNSBL providers for 3 years and not had any issues.
