Email is also the favorite mechanism of spreading assorted attacks on our computers and
networks through worms, Trojan horses, viruses, and other malware. Technology columnists,
politicians, and ordinary users declare the death of email in the face of this attack.
What can we do? Keep trying to fight the battle.
SUSE Linux 9.2 introduced a new antispam wizard that works with your email client to
remove unwanted email before it even sullies your mailbox. Several open source projects
aiming to battle spam have sprouted up, and each has its fans: SpamAssassin, Bogofilter,
SpamBayes, Assistance-Filter, and GMX are the best known. KMail and Mozilla
Thunderbird both include antispam tools. Thunderbird??™s is built in, and KMail creates
filters to work with the previously mentioned antispam tools.

procmail acts as a middleman, filtering each user??™s mail as it comes from the server, but
before it is written to the mailbox. You can configure it yourself or have one of the other
antispam tools work with it.
