• In the [kavmilter.global] section of the kavmilter.conf configuration file,
make the following changes:
ServiceSocket=unix:<socket_file_path>
or
ServiceSocket=local:<socket_file_path>

2.2. Installing Kaspersky Anti-Virus
on a dedicated server
If your mail server’s load is consistently high, it is more reasonable to install
Kaspersky Anti-Virus on a dedicated server in order to avoid server malfunction,
because anti-virus processing of mail traffic consumes considerable server
resources.
If Kaspersky Anti-Virus is installed on a dedicated server, it operates as follows:
1. The email thread arrives at the mail server with Sendmail installed.
2. Sendmail then forwards messages to Kaspersky Anti-Virus through a
network socket.
3. The processed mail thread, together with anti-virus notifications, is sent
back to the mail system for further delivery.
If Kaspersky Anti-Virus is installed on a dedicated server, you must use a
network socket for email traffic to be received and delivered via Sendmail.
Configure Sendmail as follows:
• If you use sendmail.cf, add the following lines to this file:
