DNSBL (DNS-Based Black List) and RBL (Real-time Black List) are lists of IP addresses that are suspected of sending spam and are used to prevent unwanted email messages from reaching unsuspecting recipients.
URIBL lists domains that appear in spam, NOT where they were sent from.
More information about RBL -> wikipedia
