Hello Patrick Dung, you wrote:

Whatever a user can configure for himself, the Horde administrator can also force upon his users: just set a value, and lock it, in imp/config/prefs.php (see horde/config/prefs.php for more details). When the value depends on particular circumstances, you can add the precise rules to horde/config/hooks.php.
