spamhaus

1) A spamhaus ( haus is the German word for house ) is an Internet service provider ( ISP ) or other business that allows the distribution of unsolicited commercial e-mail ( UCE ). One of the most infamous spamhauses was Cyber Promotions, an organization run by Sanford Wallace in the mid-1990s. In 1997, Cyber Promotions became one of the first such enterprises taken to court. Ordered to desist from sending unsolicited e-mails, Wallace now reportedly runs an anti-spam discussion forum.

2) The Spamhaus Project is an organization dedicated to stemming the distribution of spam. To this end, the organization publishes a list of offenders and advocates anti-spam legislation. According to an estimate from the Spamhaus Project, 200 identified servers distribute about 90% of all the spam delivered worldwide.
