E-mail has become the subject of much abuse, in the form of spamming and
e-mail worm programs. Both flood the in-boxes of E-mail users with junk
E-mails, wasting their time and money, and often carrying offensive,
fraudulent, or damaging content.
The continuing increase in spam has resulted in rapid growth in the number
of people using e-mail filtering programs, in other words software that
examines incoming email and separates spam from genuine email messages (also
called ham). Unwanted e-mail can be filtered in this way at the desktop
level (the individual user's computer) or before, for example at the network
email server/email gateway or the Internet service provider's e-mail
gateway. While network managers and ISPs can choose hardened email security
appliances or e-mail filtering services or software designed to block or
filter out both spam and viruses, desktop users are frequently limited to a
software-based solution.
