Clam
AntiVirus is a GPL
anti-virus toolkit for UNIX. The main purpose of this software is
the integration with mail servers (attachment scanning). The
package provides a flexible and scalable multi-threaded daemon, a
command line scanner, and a tool for automatic updating via
Internet. The programs are based on a shared library distributed
with the Clam AntiVirus package, which you can use with your own
software. Most importantly, the virus database is kept up to
date .

The spam-identification tactics used include:
- header analysis: spammers use a number of
tricks to mask their identities, fool you into thinking
they've sent a valid mail, or fool you into thinking you must
have subscribed at some stage. SpamAssassin tries to spot
these.
- text analysis: again, spam mails often have
a characteristic style (to put it politely), and some
characteristic disclaimers and CYA text. SpamAssassin can spot
these, too.
- blacklists: SpamAssassin supports many
useful existing blacklists, such as mail-abuse.org,
ordb.org, SURBL,
and others.
- learning classifier: SpamAssassin uses a
Bayesian-like form of probability-analysis classification, so
that a user can train it to recognise mails similar to a
training set.
- distributed hash databases: Vipul's
Razor, Pyzor
and DCC
are collaborative spam-tracking databases, which work by
taking a signature of spam messages. Since spam typically
operates by sending an identical message to hundreds of
people, these databases short-circuit this by allowing the
first person to receive a spam to add it to the database -- at
which point everyone else will automatically block it.

The 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.

The Spamhaus Exploits Block List (XBL) is a
realtime database of IP addresses of illegal 3rd party exploits,
including open proxies (HTTP, socks, AnalogX, wingate, etc),
worms/viruses with built-in spam engines, and other types of
trojan-horse exploits.
