Licensing

The SCOoffice Mail Server provides user (client) licenses for a given number of mailboxes allowed on the system. The basic configuration includes user licenses for 25 mailboxes, sufficient for standard configuration and small-scale mail service. Consult your software vendor to purchase incremental user license bundles ("bump packs") as needed.

When the number of SCOoffice Mail Server mailboxes exceeds that for which the product has been licensed, the administrator must purchase additional licenses. The system will allow user access even when the user limit has been exceeded.

The SCOoffice Mail Server can be installed and licensed on SCO Linux, Caldera OpenLinux, and UnixWare 7 with Linux Kernel Personality platforms.
