The Spamhaus Block List
The Spamhaus Block List (SBL) is a realtime database of IP addresses of verified spam sources (including spammers, spam gangs and spam support services), maintained by the Spamhaus Project team and supplied as a free service to help email administrators better manage incoming email streams.
The SBL is queriable in realtime by mail systems thoughout the Internet, allowing email administrators to identify or block incoming connections from IP addresses involved in the sending of Unsolicited Bulk Email.
The SBL database is updated 24/7 by a dedicated international Spamhaus team (US, UK, NL, I, JP, AR) and is broadcast by 32 SBL zone mirror servers based in Australia, Belgium, Denmark, Germany, Greece, Italy, Japan, Netherlands, South Africa, UK and USA. Spamhaus also supplies direct hourly Datafeeds of the SBL to many of the Internet's major Internet Service Providers, Corporations, Universities, Government and Military networks.
