Killing the Corporate Hydra: Spam E-Mail

domains, from which e-mail is always accepted;
even if a whitelisted domain is on a blacklist). It
offers the additional versatility of two layers of
whitelists and blacklists. The administrator sets the
standards at the server level to determine spam email
for everyone in the organization using the
global whitelist and blacklist settings, while
individuals are able to supplement the rule set at
the desktop by defining their own whitelist or
blacklist entries.

This functionality is especially important because
what one user or company might classify as spam,
another may want to receive. For example, an
associate in a law firm working on a case
concerning Viagra can create her own whitelist to
let through e-mails from specific clients or domains.
Self-Tuning: The SpamKiller engine is able to learn
the characteristics of typical e-mail users receive,
interpreting that information to adjust the spam
score given to incoming e-mail messages—a
process also known as “auto-white listing.” The
self-tuning functionality works out the statistical
distribution of the overall spam rating for e-mail
sent by each individual sender, and uses this to
adjust the overall spam rating for new messages
sent by a known sender.

For example, a user may have a vendor who
regularly sends (non-spam) e-mail. The vendor may
forward a virus alert that might ordinarily be given a
high overall spam rating due to its formatting. Here,
the SpamKiller product will use historic data
provided by the SpamAssassin engine to lower the
message’s overall spam rating so it doesn’t get
classified as spam.

Together, these capabilities make McAfee SpamKiller a
top choice for both small businesses and larger
enterprises struggling to eradicate spam.
