Performing initial configuration in Kerio Connect

About initial configuration

Before you start using Kerio Connect, you must perform an initial configuration.

The initial configuration sets the basic parameters for Kerio Connect. These include:

The wizard creates special files where the server configuration is saved.

Configuration files

During the initial configuration, the following configuration files are created:


users.cfg is an XML file with the UTF-8 coding which includes information about user accounts, groups and aliases.


mailserver.cfg is an XML file with the UTF-8 coding which contains any other parameters of Kerio Connect, such as configuration parameters of domains, back-ups, antispam filter, antivirus.

The default location of the configuration files is:

  • Windows: C:\Program Files\Kerio\MailServer

  • Mac: /usr/local/kerio/mailserver

  • Linux: /opt/kerio/mailserver

On Mac OS X and Linux systems, files can be maintained only if the user is logged in as the root user.
