CHAPTER 4. KASPERSKY ANTI-
SPAM OPERATION AND
FILTERING PHILOSOPHY
4.1. Configuring filtering settings
Kaspersky Anti-Spam provides you with powerful tools for detecting spam in the
incoming e-mail traffic. Actions with suspicious messages may range from most
severe (rejection) to quite moderate (e.g., adding an extra header to the
message for further processing by the e-mail program). The mail service
administrator decides which actions should be applied to a particular spam type.
The Kaspersky Anti-Spam distribution kit includes a set of preinstalled filter
profiles that ensure effective spam filtering and provide alternative means for
processing detected spam messages (for more details see para 4.4, page 35).
Filtering rules and profiles as well as the order of their application can be
modified by the system administrator via WebConfigurator (see Chapter 5,
page 47). In addition, the administrator can enable and disable particular profiles
via WebConfigurator.
Editing of filter profiles should be performed with extreme care as even
minor changes may result in serious undesirable consequences such
as false filter triggering or decreased spam detection quality.
All filter operation settings are configured using a convenient web interface
provided by WebConfigurator.
Description of WebConfigurator operation and filtering settings configuration are
described in Chapter 5, page 47.

use philosophy before you start using these rules (see para 4.3,
page 25).
