Kaspersky Lab kaspersky anti-spam 2.0 Manual

 – a randomization indicator for the filtering 

process work completion after receiving the SIGHUP signal. The default 
value is: 0. 

If the value of H is non-zero, then the filtering process completes upon 
the receipt of the signal with a random delay from 0 to H-1 seconds. 
This parameter is used in order to avoid the development of peak loads 
at the times when all filtering processes simultaneous restart (for 
example when the filter configuration is recompiled or the filtering 
database is updated). 

A.3. Client modules for mail systems 

Client modules included in the Kaspersky Anti-Spam software package are used 
for the program integration into the mail systems installed on the user's 
computer. 

The following modules are used for the supported mail systems: 

•  kas-milter – for the Sendmail mail system. 

•  kas-pipe – for the Postfix mail system. 

•  kas-pipe (standard setup) – for the Exim mail system. 

•  kas-exim (alternative setup) – for the Exim mail system. 

•  kas-qmail – for the Qmail mail system. 

•  kas-cgpro – for the Communigate Pro mail system. 

The integration operations required are performed during the installation of 
Kaspersky Anti-Spam using mail system configuration scripts. 

This section contains a detailed description of the operation of the client 
modules, their configuration files and the peculiarities of the mail systems 
configuration. 

A.3.1. Interaction of the client modules 

with the filtering service 

All client modules interact with the filtering service using one common procedure: 

• 

the client receives a message from the mail system; 

• 

the client sends a request to connect with the filtering process;
