Killing the Corporate Hydra: Spam E-Mail

III. SpamKiller for Microsoft Exchange
Small Business

McAfee SpamKiller for Microsoft Exchange Small
Business is the first of the SpamKiller family to be
released. Additional products will become available,
offering SpamKiller protection at the gateway, server,
and desktop, in the second half of 2003.

This solution is ideal for small businesses that require
enterprise-caliber spam protection. Designed for ease
of deployment and low-maintenance administration,
SpamKiller for Microsoft Exchange incorporates the
SpamAssassin rules-based scanning and five methods of
detection. In addition, its special features include:

• The ability to auto-create an end user “Junk
Mail” folder: System administrators have the
option of sending e-mail identified by SpamKiller as
spam to either a junk mail folder in Microsoft
Outlook, or a system junk mail folder. The first time
a spam-rated e-mail is sent to an end user’s inbox, a
“junk mail” folder can be automatically created.
Thereafter, all e-mail rated as spam goes to the junk
mail folder rather than to the inbox. This feature
makes for a very streamlined installation; the
Exchange Administrator is not required to write any
rules. It also immediately gets spam out of the end
user’s inbox, and moves the responsibility for
reviewing junk mail from the system administrator
to the end user.

• Auto-sync to Outlook Contacts: The system will
automatically synchronize to an end user’s Exchange
Contacts folder to create a default personal whitelist.
Additions or deletions to Contacts will be
synchronized to the personal whitelist, avoiding the
potential for legitimate e-mails to be falsely
identified as spam. The end user, if given
permissions, can then use a Web interface to view
and edit the whitelist and blacklist. Auto-sync with
Outlook Contacts quickly and easily lowers the false
positive rate without the involvement of the end-user
or the system administrator having to get involved.

• Tiered routing of spam e-mails: The system
administrator can set up tiered routing of e-mails,
so e-mails scoring under a certain threshold (default
is five) are sent to the system junk mail folder. For
example, e-mails with scores of less than five will go
to the inbox, those between five and fifteen will go
to the junk mail folder in the inbox, and e-mails with
scores larger than fifteen will go to a system junk
mail folder. A tiered routing approach sends
questionable e-mail can go to the end user for
