Not Just Another Bogus List blacklist details

Description

NJABL (Not Just Another Bogus List) is a DNS based blacklist. NJABL blacklist started out due to dissatisfaction with the quality and ethics of other DNS blacklists.

NJABL.org maintains DNS zones of spam sources (open relays, open proxies, insecure web forms, dynamic IP pools, direct spammers), provides stable DNS blacklist with clear and strict listing criteria. NJABL.org has instructions and tools which allow end users to contribute.

Listing criteria

IP address could be blacklisted by being an open relay or proxy, being part of dynamic IP pool or allows or supports spamming in some way.
