Barracuda RBL
From Hostek.com Wiki
Barracuda Networks maintains the Barracuda Reputation Block List (BRBL) as a free DNSBL of IP addresses known to send spam. Barracuda Networks fights spam and created the BRBL to help stop the spread of spam.
To use Barracuda's RBL you'll need to register for an account: http://www.barracudacentral.org/account/register
