More Information About Rsbl

Realtime Spammers BlackList (RSBL) - This blacklist is currently in "frozen" status for an unspecified time period, however the database still returns results. RSBL is part of ANTISPAM-UFRJ, the official antispam website of the Laboratory for the Processing of Analog and Digital Signals (PADS/COPPE/UFRJ). The ANTISPAM-UFRJ is a realtime database with the mission to supply the Mail Transport Agents (MTA) of the hosts in the PADS and in others networks with the most recent information about open-relay hosts, spammers hosts or dialup machines on the Internet.
