Not Just Another Bogus List, or NJABL, is a DNS blacklist
.
NJABL maintains a list of known and potential spam sources (open mail relays, open proxies, open form to mail HTTP gateways, dynamic IP pools, and direct spammers) for the purpose of being able to tag or refuse e-mail and thereby block spam
from certain sources. NJABL automatically retests only listed open relays every 90 days .
The Open Proxy IPs portion (only) of NJABL data are used in Spamhaus

NJABL's dynamic IP list originally came from Dynablock
