CHAPTER 5. CONFIGURING
FILTERING PARAMETERS
Kaspersky Anti-Spam provides mail server administrator with powerful and
convenient tools for user protection from unwanted mail (spam). Filtering logic is
not forced by the filter – the administrator is able to set it independently in
accordance with his/her company’s policy and mail recipients’ requirements.
Since the operation of Kaspersky Anti-Spam is completely defined by
the settings specified by the administrator, we recommend that you pay
particular attention to this process. Improper setup can result in:
• ineffective filter operation (most unwanted messages pass through
the filter).
• The loss of normally allowed e-mails.
All filtering parameters are set via WebConfigurator, that allows creation, editing,
and deletion of:
• Filter profiles (sets of rules) both common (valid for all users), and
personal (valid for some individual users or their groups).
• Filtering rules (conditions and corresponding actions), controlling their
application procedure.
• Black and white IP address and e-mail lists that filtering rules can refer to.
• DNS-based RBL lists.
Read the instructions on filter operation principles before you begin
configuring the settings (see para 4.3, page 25). Pay special attention to
description of the filter operations (see para 4.3.3, page 28) and to the
order of profiles and filtering rules application (see para 4.3.4, page 31).
Study the sample filter profiles supplied with the program.
You can work with WebConfigurator from a remote location using any web
browser.
5.1. Starting WebConfigurator
The Kaspersky Anti-Spam software package includes thtppd server (installed as
kas-thhtpd). This server starts on port 2880 and provides access to
WebConfigurator via http protocol.
