28 Kaspersky Anti-Spam 2.0 Enterprise Edition / ISP Edition
Linguistic lab of Ashmanov & Partners JSC is constantly working on the
enhancement and updating of the content filtering database. Therefore,
it is recommended that you regularly update the database (see Chapter
6, page 89). System administrator can also add new spam message
examples to the database (see para 5.2.6, page 82).
Based on the results of the content analysis, a message may be assigned one or
several index categories of the content filtering database.
Configuring filtering rules using WebConfigurator (Chapter 5, page 47), the
system administrator should set up rules for processing e-mail messages related
to various index categories

.
While configuring the program, the system administrator must give the
first priority to saving all "useful" e-mail messages as the loss of just
one important message may be much more harmful to the user than
receiving dozens of unwanted messages. To avoid the loss of
necessary data, it is recommended to apply only moderate processing
actions to the messages "rejected" based on the results of the content
analysis. For example:
• add warning [Spam] to the Subject header;
• add an extra header Keywords=... that will allow users to redirect
such messages to the special folders of their mail clients.
4.3.3. Actions to be applied to messages
If the conditions described in a filtering rule (see para 4.3.1, page 26 and
para 4.3.2 page 27), are met for a certain message, then actions described in
this rule will be applied to such message.
The actions can be:
• "severe" – these actions terminate message processing;
• "moderately severe" – these actions stop execution of the rule and of all
other rules of the current profile, although rules of other profiles can be
applied to a message;
• "moderate" – when this action is complete, other actions of the current
rule will still be applied as well as other rules of the same and/or of other
profiles.

If a message is assigned one of the index categories, it does not necessarily mean that
the message contains spam. For example, a message containing indecent vocabulary will
be assigned the Obscene category. System administrator can ignore it (not specify it in the
rule conditions).
