CHAPTER 9. COMPATIBILITY
WITH OTHER KASPERSKY
LAB APPLICATIONS
Kaspersky Anti-Virus 5.6 for Sendmail with Milter API does not cause any
compatibility problems when running concurrently with the following Kaspersky
Lab applications for Unix/Linux platforms:
• Kaspersky Anti-Virus 5.0.3-0 for Samba Servers.
• Kaspersky Anti-Virus 5.5-2 for Linux Workstation.
• Kaspersky SMTP-Gateway 5.5 for Linux/Unix Maintenance Pack 1.
When using a Kaspersky Lab application for Unix/Linux that has the real-time
protection component kavmonitor, note that the Sendmail message queue is
stored on a hard disk and, when a queued message is accessed, kavmonitor
intercepts this message. If the message is infected or contains suspicious code,
the kavmonitor component will block this message and prevent it from delivering.
To avoid this problem, we advise that you exclude the Sendmail queue directory
from the kavmonitor scan area.
During installation of Kaspersky Anti-Virus for Sendmail with Milter API on the
same server that Kaspersky Anti-Virus for Unix/Linux is on, the kavmilter module
is registered in the kavmonitor module using a special script. After the
registration, the kavmilter module receives "permission" from kavmonitor to filter
Sendmail messages.
To filter email messages, Kaspersky Anti-Virus for Sendmail with Milter API
creates a temporary file in the specified directory on the disk. The kavmonitor
module intercepts this file to perform anti-virus processing. If the file is flagged as
infected, the kavmonitor component will block this message and prevent
Kaspersky Anti-Virus for Sendmail from filtering it (signal mlfi_abort).
To avoid the problem, we recommend that you exclude the directory for
Kaspersky Anti-Virus for Sendmail temporary files from the kavmonitor scan
area.
The temporary file directory is defined by the TempDir parameter in the
[kavmilter.global] section.
