This document is a simple guide focused on description of Kerio MailServer configuration applied immediately upon its first installation and startup in the network. To make the guide as comprehensible as possible, let us see an exemplary implementation of Kerio MailServer (see figure 1.1  Example of Kerio MailServer implementation):

  1. Install Kerio MailServer on a separate server (no other services will be run on it) and run it in a local firewall-protected network.

  2. Kerio MailServer will be connected to the Internet via a leased line. Email will be received and sent vie SMTP. For this reason, it is necessary to enable antivirus and antispam control.

  3. Kerio MailServer will be used for a single domain called company.com. The server will be installed and run in the local network, on a host with IP address 192.168.1.10 and DNS name mail.company.com.

  4. In the internal user database, there will be created only one local account used for administration of Kerio MailServer. Any other user accounts will be mapped from the Microsoft Active Directory directory service (the same method can be used for the Apple Open Directory).

    Name of the Active Directory domain will be the same as the name of the email domain and the name of the Kerberos realm.

  5. The server will be available both from the local network and from the Internet. For security reasons, however, only SSL/TLS-secured Internet connections will be allowed.

  6. All undelivered email (messages where the part preceding the @ symbol in the address is not valid) will be sent to admin@company.com.

  7. Enable the Kerio MailServer's dual antivirus control. We will use the integrated McAfee antivirus (license of Kerio MailServer with McAfee is required) and the external Clam AntiVirus which will be installed on the same computer as Kerio MailServer.

  8. All email will saved and backed-up in a local archiving folder once a week.

  9. Users will access their email via Kerio WebMail, MS Outlook extended with the Kerio Outlook Connector and with the Kerio Synchronization Plug-in. MS Entourage will be used on Mac OS X..

The exemplary configuration can be easily customized. For detailed information on setting of individual features of Kerio MailServer, refer to Kerio MailServer, Administrator's Guide, chapterDeployment Examples.
