Important! After you upgrade Kaspersky Security 8.0 for Linux Mail Server, an encrypted connection with the LDAP server (TLS or LDAP over SSL) is established by default. If you need an unencrypted connection with the LDAP server, configure it manually after upgrading Kaspersky Security 8.0 for Linux Mail Server.

• After Kaspersky Security 8.0 for Linux Mail Server is upgraded, the settings in the klms_filter.conf file are overwritten with default settings. Save a backup copy of the klms_filter.conf before upgrading Kaspersky Security 8.0 for Linux Mail Server. After completing the upgrade, transfer the relevant settings from the backup copy to the new file.
• If the Backup directory is located on a hard drive partition with the NFS file system, message processing may be slowed down due to NFS problems. We recommend enabling a timeout for placing messages in Backup or mounting the partition in soft mode.
• If you are unable to use the Backup database included in the application distribution kit, you can use the already deployed PostgreSQL database of version 9.1 or later. For information on migrating to new Backup, refer to the Kaspersky Security 8.0 for Linux Mail Server Knowledge Base on the Technical Support website.
• If you integrate Exim dlfunc under an operating system that uses systemd technology for initialization, the temporary folder of Kaspersky Security 8.0 for Linux Mail Server is created at the following path /var/opt/kaspersky/klms/tmp instead of /tmp. If the tmpfs file system has been used for the /tmp folder, you have to reconfigure the file system of the /var/opt/kaspersky/klms/tmp folder manually.
