The CBL takes its source data from very large spamtraps/mail infrastructures, and only lists IPs exhibiting characteristics which are specific to open proxies of various sorts (HTTP, socks, AnalogX, wingate etc) which have been abused to send spam, worms/viruses that do their own direct mail transmission, or some types of trojan-horse or "stealth" spamware, dictionary mail harvesters etc.

I have scanned all of them to see if they are doing anything they shouldn't be - using usual malware scanners, etc. So far I have found nothing. What can I do to find out where this is coming from? CBL simply has not responded to me so I don't even know what evidence they have to support the blacklisting. This is the most frustrating part of this whole thing. They keep blacklisting me, and they won't talk to me!
