CHAPTER 5. ADVANCED
APPLICATION SETTINGS
This chapter discusses in detail the advanced settings of Kaspersky SMTP-
Gateway. In contrast to main settings (see section 4.2 on page 31), that provide
the application functionality, advanced settings can be configured optionally at
the administrator’s discretion.
5.1. Configuring anti-virus protection
of mail traffic
Application settings in the [smtpgw.ave] section define the mode of message
scanning and disinfection, configure the use of the iChecker technology for
acceleration of anti-virus processing and enable or disable scanning of archives
or e-mail databases (as determined by the ScanArchives and ScanMailBases
options respectively).
5.1.1. Scanning and disinfecting messages
By default, the application only scans your email traffic for viruses. If a virus is
detected, the application can delete such infected object, rename it, block
messages, deliver message containing such object and/or send notifications to
the sender, recipient, and administrator. To enable disinfection, set the Cure
parameter to true.
To have Kaspersky SMTP-Gateway disinfect infected messages, specify the
Cure=true value. If disinfection has been successful, the object is assigned the
Disinfected status.
5.1.2. Using the iChecker™ technology
While performing anti-virus scan, the application may use the iChecker™
technology (UseIChecker parameter, section [smtpgw.ave]) that eliminates the
need to scan identical objects each time they are detected in the flow of email
messages and, if possible, perform only one comparison with the existing data.
The object anti-virus scan algorithm will be changed as follows:
