Application Overview Kaspersky Anti-Virus 5.5 for Linux and FreeBSD Mail Servers (hereinafter referred to as Kaspersky Anti-Virus) provides anti-virus processing of mail traffic and file systems of servers running the Linux or FreeBSD operating systems, and using the sendmail, postfix, qmail, or exim mail programs. This software application allows the user to: * Scan for viruses incoming and outgoing mail messages, as part of the server's SMTP traffic. * Detect infected, suspicious, corrupted, and password-protected files, as well as files that cannot be scanned. * Cure infected objects of file systems and e-mail messages. * Quarantine all infected, suspicious, and corrupted objects of the server file system and its mail traffic. For the latter, password-protected files can also be quarantined, as well as files that cannot be scanned. * Process mail traffic according to rules preset for groups of senders and recipients. * Provide secondary filtering of mail traffic by name and type of attached files, and use individual processing rules for the filtered objects. * Notify the sender, recipient, and group administrator about mail messages that contain infected, suspicious, and other objects. * Update the anti-virus databases downloading update files from Kaspersky Lab's update servers. * Scan for viruses all mounted file systems. * Configure Kaspersky Anti-Virus via the web based interface provided by the Webmin program and the application configuration file.

Application Installation & Upgrade Kaspersky Anti-Virus 5.5 during installation does not remove the existing versions of Kaspersky Anti-Virus. It changes only files essential for operation of version 5.5; in particular, the installer removes the settings of earlier (5.0) versions from mail server configuration. In addition, the installer also replaces startup scripts to avoid conflict between aveserver versions. The setup procedure allows import of settings from previous versions into version 5.5. Migration from earlier version of the application (Kaspersky Anti-Virus 5.5 for Linux and FreeBSD Mail Servers MP2) -------------------------------------------------------------------------- We recommend the following method for application upgrading:
1. Save the application configuration file if it has been modified by
the administrator while working with the product.
2. Uninstall the existing application version using the method described
in the included Administrator's Guide. If the Webmin module has been
installed it should be removed using Webmin administration tools.
3. Install this application version using the method described in the
included Administrator's Guide.
4. Replace the default application configuration file
(/etc/kav/5.5/kav4mailservers/kav4mailservers.conf) with the file
saved during step 1.
General Issues & Workarounds * Automatic removal of Kaspersky Anti-Virus with restoration of the original configuration will be impossible in cases when the product is installed together with Kaspersky Anti-Spam 2.0 and the latter has been installed after Kaspersky Anti-Virus. * Proxy Server parameters are not imported in cases, when import of settings from an earlier version has been selected during installation. * In cases when the product is installed together with Kaspersky Anti-Spam 2.0 and integrated with postfix, their interaction requires that the kas-pipe and smtpscanner processes must be started by the kluser user. To do so, change the mailft user to kluser in the master.cf configuration file after installation and configuration of the applications. E.g., replace the line: 127.0.0.1:9026 inet n n n - 20 spawn user=mailflt argv=/usr/local/ap-mailfilter/bin/kas-pipe -c /usr/local/ap-mailfilter/etc/kas-pipe-postfix.conf with the following line: 127.0.0.1:9026 inet n n n - 20 spawn user=kluser argv=/usr/local/ap-mailfilter/bin/kas-pipe -c /usr/local/ap-mailfilter/etc/kas-pipe-postfix.conf * If a Linux Mandrake 10.1 system uses security level value higher than
normal, you will have to change manually the owner of the directory
specified for recording of the log files running the following command
after installation:
chown kluser:klusers /var/log/kav/5.5/
* In some distributions exim is by default supplied without LMTP support. Since the number of these modifications is very large and constantly increasing, the experts of Kaspersky Lab guarantee operation of Kaspersky Anti-Virus with the stable official Exim version only built using the TRANSPORT_LMTP=yes option in Local/Makefile. * In case of integration with exim in systems based on RHEL-3, you will have
to add manually to the "kav_lmtp_transport" section of the
/etc/exim/exim4.conf.listen file the following line after installation:
home_directory = /var/db/kav
* In case of Kaspersky Anti-Virus integration with exim and subsequent installation of Kaspersky Anti-Spam 3.0 the host system will only run anti-spam checks; anti-virus scanning will not be performed. * Certain issues have been reported for installation of Webmin plug-in modules with Webmin version included into Debian GNU/Linux 3.0 and Linux Mandrake 10.1. You are advised to update Webmin before installing Kaspersky Anti-Virus. For Linux Mandrake 10.1 installation of Webmin from a tar.gz package available at www.webmin.com is recommended. * Names of detected and disinfected viruses appear twice in anti-virus statistics (as detected and cured objects), resulting in incorrect reflection of virus statistics within Webmin. * You are advised to use Latin letters and digits only in group names in the application configuration file. Other characters may cause problems while using the Webmin plug-in module to configure the application. * If you are using the Quarantine feature with e-mail messages, make sure that the kluser user has write access to the quarantine directories defined by the QuarantinePath parameters in the [smtpscan.group:*] sections of the configuration file.
