SMTP-Gateway 5.5 for Linux/Unix
Question: Can an intruder deliberately replace the anti-virus databases?
Every anti-virus database has a unique signature verified by Kaspersky
products while accessing the database. If the signature does not
correspond to the one assigned at the Kaspersky Lab, or the date of the
database is later than that of the license expiry, Kaspersky SMTP-
Gateway will not use it.
Question: The application cannot be started, the Sender module does
not work, etc. What should I do?
If, due to incorrect settings, the number of running processes (threads)
exceeds the maximum number permitted by the system, the application
performance may be affected or your system will freeze. To solve this
problem, it is recommended to decrease the number of concurrently
active incoming and outgoing mail sessions and the number of objects
scanned simultaneously by the AV module (AntiviralSessions,
IncomingSessions, and OutgoingSessions parameters in the
[smtpgw.limits] section of the application configuration file).
The second solution for the problem would be to decrease the stack
size.
This command works in Linux operating system only.
Enter the following in the command line:
# ulimit –s
The maximum stack size will be displayed on the console. Set the new
value equal to the quarter of the current value by entering the following:
# ulimit –s <number>
where <number> is a new maximum stack size.
Question: What should I do to make man pages of the application
available by the command man <name>?
To make application man pages available using man <name>
command at each restart of your system, do the following:
• For Debian and SuSE Linux distributions, the following line
should be added to the /etc/manpath.config file:
MANDATORY_MANPATH /opt/kav/5.5/smtpgw/man
