6.1.3. Setting performance restrictions 

Kaspersky Mail Gateway provides the administrator with the possibility to setup 
certain limits when working with the application. In some cases, this may help 
reduce the load on your server and increase performance. In addition, using 
network restrictions, it is possible to prevent some types of virus outbreaks and 
DOS attacks aimed at paralyzing your mail server with huge volumes of mail 
traffic.  

 

You can find all restriction settings in the [smtpgw.limits] section 
of the application configuration file.  

You can set the following restrictions: 

• 

Number of objects simultaneously processed by the Receiver, Sender 
and the AV modules (the  IncomingSessions,  OutgoingSessions, and 
AntiviralSessions options, respectively). 

• 

Maximum number of message hops (MaximalIncomingHops option). 
Set this parameter to avoid looping due to incorrect configuration of the 
routing table.
