Operation On A Dedicated Server - KAPERSKY ANTI-VIRUS 5.5 - FOR LINUX-FREEBSD MAIL SERVERS Administrator's Manual

14
Let us take a detailed look at the operation of Kaspersky Anti-Virus on the same
server as any of the above mentioned mail systems (see Figure 2). The
sequence of processing incoming and outgoing mail is identical, and consists of
the following stages:
1. The stream of mail messages comes in from other servers, or from the
LAN, via the SMTP protocol.
2. The mail system receives the mail traffic and passes it to Kaspersky
Anti-Virus for scanning.
3. The application processes the mail traffic according to the specified
settings, and returns it to the mail system along with an additional set of
notifications.
4. The mail system routes the mail traffic further.
Based on the above diagram, during installation or post-installation configuration
of Kaspersky Anti-Virus, the following settings must be adjusted:
•
Define the port which Kaspersky Anti-Virus will use.
•
Set the mail system port that the program will use to receive mail from
Kaspersky Anti-Virus after filtering.

2.3. Operation on a dedicated server

Kaspersky Anti-Virus for Linux and FreeBSD Mail Servers can scan and provide
anti-virus processing, for mail traffic even if your mail server is running another
operating system, for example Microsoft Windows Server 2003.
