CHAPTER 4. RECOMMENDED
OPERATION MODES
In addition to
kavmilter.
conf, the Kaspersky Anti-Virus for Sendmail with Milter
API distribution kit includes four configuration files that provide four protection
levels for your mail server:
kavmilter-high-security.conf
– Application configuration that delivers a high
overall protection to your e-mail traffic (see section 4.1 on page 23).
kavmilter-high-accuracy.conf
– Application configuration that provides
maximum protection for your e-mail traffic (see section 4.2 on page 24).
kavmilter-default.conf
– Configuration that provides an optimal balance be-
tween protection level and performance efficiency. When this configura-
tion is enabled, the application runs seamlessly on your mail server, al-
lowing you to work with other applications (see section 4.3 on page 25).
The default configuration file,
kavmilter.conf
, is a copy of this file.
kavmilter-high-scanspeed.conf
– With this configuration, the program scans
e-mail traffic at its fastest, sacrificing functionality for speed (see sec-
tion 4.4 on page 25).
The administrator can edit any of these files to tailor the application to fit your
company needs and environment.
After installation, all these files are stored in the
/etc/kav/5.0/kavmilter/profiles
directory.
These options are described in more detail below.
4.1. High overall security mode
This mode offers the most comprehensive protection of your mail traffic. In this
mode, the program notifies senders, recipients, and administrator about scan
results. This mode includes the following functions:
•
The program scans e-mail messages using a combined scan policy:
every letter is first scanned for viruses on the whole and then each mes-
sage object is scanned separately, regardless if the infected objects found
or not.
•
E-mail messages are filtered by MIME type, attachment name and size,
and also by virus name.
