>> <http://www.spamhaus.org/zen/>Has anyone had a confirmed false positive with zen.spamhaus.org ?
>> zen blocks these categories:
>> SBL Direct UBE sources, spam operations & spam services
>> CSS Direct snowshoe spam sources detected via automation
>> CBL (3rd party exploits such as proxies, trojans, etc.)
>> PBL End-user Non-MTA IP addresses set by ISP outbound mail policy
>> SBL and CSS are confirmed spammers. CBL are confirmed exploited machines. PBL are IPs that the IP owner has classified as not allowed to send mail directly.
>> Blocking all of those is perfectly safe.
> Perfectly safe is the categorizing process is itself perfect.
> ANd since nothing is perfect, you'll always have false positive.
