The Spamhaus Project is responsible for compiling several widely [2] used anti-spam lists. Many [3] internet service providers and email servers use the lists to reduce the amount of spam that reaches their users.

The lists are offered as a free public service to low-volume mail server operators on the Internet. The Spamhaus Block List SBL [8] targets "verified spam sources including spammers, spam gangs and spam support services. The PBL lists not only dynamic IP addresses but also static addresses that should not be sending email directly to third-party servers.

Examples of such are an ISP 's core routers, corporate users required by policy to send their email via company servers, and unassigned IP addresses. It lists spam domains including spam payload URLs, spam sources and senders "right-hand side"known spammers and spam gangs, and phish, virus and malware -related sites.

It later added a zone of "abused URL shortners", a common way spammers insert links into spam emails. Such infrastructure is commonly used by cybercriminals to control malware infected computers.

The SWL is intended to allow mail servers to separate incoming email traffic into 3 categories: Good, Bad and Unknown. Only verified legitimate senders with clean reputations are approved for whitelisting and there are strict terms to keeping a Spamhaus Whitelist account.

It is intended to be incorporated in firewalls and routing equipment to drop all network traffic to and from the listed blocks. The Spamhaus Project consists of a number of independent companies which focus on different aspects of Spamhaus anti-spam technology or provide services based around it.

At the core is The Spamhaus Project Ltd. Further companies include Spamhaus Logistics Corp. Spamhaus Technology Ltd. Spamhaus Research Corp. The Spamhaus Whitelist Co.

Spamhaus had the case moved from the state court to the U.

Federal District Court for the Northern District of Illinois and asked to have the case dismissed for lack of jurisdiction. Spamhaus subsequently announced that it would ignore the judgement because default judgements issued by U. Following the ruling in its favour, e filed a motion in Federal court to attempt to force ICANN to remove the domain records of Spamhaus until the default judgement had been satisfied.

The court further ruled that removing Spamhaus's domain name registration was a remedy that was "too broad to be warranted in this case", because it would "cut off all lawful online activities of Spamhaus via its existing domain name, not just those that are in contravention" of the default judgment.

This does not work.
