I don't think any blacklist operator will claim that their blacklists have no false positives. The false positives vary by list. Some have more, some have fewer, and their characteristics may vary between lists. It's a responsibility of the mail administrator user of the blacklists to understand the differences and use the tools appropriately. Jeff C.
