Vipul's Razor is what you now commonly know as SpamNet. For nearly two
years, Razor has been successfully fighting spam with the help of the
Unix community and is the technology that has enabled us to build its
windows counterpart, SpamNet, currently in use by more than 100,000
users. Razor, or SpamNet, is a distributed, collaborative, spam
detection and filtering network. It establishes a distributed and
constantly updating catalogue of spam in propagation. This catalogue is
used by clients to filter out known spam. Upon receiving a spam, a
Reporting Agent (run by an end-user or a troll box) calculates and
submits a 20-character unique identification of the spam (a SHA Digest)
to its closest Catalogue Server. The Catalogue Server echoes this
signature to other trusted servers after storing it in its database.
Prior to manual processing or transport-level reception, Filtering
Agents (end-users and MTAs) check their incoming mail against a
Catalogue Server and filter out or deny transport in case of a signature
match. Catalogued spam, once identified and reported by a Reporting
Agent, can be blocked out by the rest of the Filtering Agents on the
network.

SpamAssassin is a mail filter which attempts to identify spam using text
analysis and several internet-based realtime blacklists.
Using its rule base, it uses a wide range of heuristic tests on mail
headers and body text to identify "spam", also known as unsolicited
commercial email.
Once identified, the mail can then be optionally tagged as spam for
later
filtering using the user's own mail user-agent application.
SpamAssassin typically differentiates successfully between spam and
non-spam in between 95% and 99% of cases, depending on what kind
of mail you get.
SpamAssassin also includes support for reporting spam messages
automatically, and/or manually, to collaborative filtering databases
such as Vipul's Razor [1].
