2.4 InstallationKerio MailServer Engine, which is the mail server’s core, running as a service, will be startedimmediately after the installation is complete. This implies that a utility called KerioMailServer Monitor will also be run, by which you can view the Engine status, stop or startthe mail server and perform other tasks. Kerio MailServer Monitor is displayed as an iconin the SysTray (see figure 2.8).Figure 2.8Kerio MailServer Monitor on WindowsProtection of the installed productIn order to ensure the maximum security of the mailserver, it is necessary to disallowunauthorized access to the application files (in particular to the configuration files). If theNTFS file system is used, the system resets the access rights to the directory where KerioMailServer is installed (including all subdirectories — even if the path has changed) uponthe first startup after each upgrade or installation: the read and write access is allowedonly for members of the Administrators group and the local system account (SYSTEM); noone else is allowed to access the system files.Warning: If the FAT32 file system is used, it is not possible to protect Kerio MailServerin the above way. Thus, we strongly recommend to install Kerio MailServer only on NTFSdisks.LinuxKerio MailServer supports the following distributions of the Linux operating system:• Red Hat 9.0• Red Hat Enterprise Linux 3 / 4 / 5• Fedora Core 4 / 5 / 6 / 7 / 8 (on 32-bit systems)Requires: libstdc++.so.5 (compat-libstdc++-33 RPM package)Fedora Core 5 requires: compat-gcc-32-3.2.3-56.fc5 and compat-libstdc++-33-3.2.3-56.fc5.• SuSE Linux 10.0, 10.1, 10.2 and 10.3 (32-bit)Requires: libstdc++.so.5 (compat-libstdc++-33 RPM package)Kerio MailServer is distributed in two RedHat Package Manager packages — the server and theadministration console.Warning: For installations, Kerio MailServer uses the RPM application.
