52 Kaspersky Anti-Virus® for Sendmail with Milter API
viruses that are not yet in the database. The use of heuristic technology is
defined by the ScanCodeAnalyser parameter in the [kavmilter.engine]
section.
• Set the time the application will use to scan a message or a message
object.
The maximum scan time (in seconds) for a message or a message object
is specified by the MaxScanTime parameter and is ten seconds by
default. If the application fails to scan the object within this time, it will
assign Error status to such object.
• Define the number of objects which can be simultaneously scanned for
viruses.
The administrator can limit the number of simultaneous scan requests by
specifying the MaxScanRequests parameter. The default value is zero
(unlimited). Use this limitation only if anti-virus scanning has a significant
impact on the server.
7.6. Selecting objects to scan
During anti-virus processing of server mail traffic, the application scans all mail
attachments for viruses.
Since scanning archives and compressed executables requires significant time
and server resources, the administrator can decide whether to enable or disable
the analysis of such files for viruses.
It is not recommended to disable this option, since it will significantly
decrease protection level.
Scan options for archives and compressed executables are defined by the
ScanArchives and ScanPacked in the [kavmilter.engine] section. By default,
the application scans these types of files.
Attention! The application is unable to detect viruses in password
protected archives! This attachment is flagged as Protected and further
actions applied to it are defined by the ProtectedAction parameter of
the [group.actions] section.
