When configuring a Callimachus server you can change its state via the Web interface. You have five options: OfflineStartingRunningStopping, and Stopped. Each of these indicate a distinct state of the server. When the Edit template is loaded (on read), the value represents the current state of the server. When the Edit template is saved (on write), these values are interpreted as follows:

State Description
Offline Stops the server before applying Mail and New Realm changes.
Starting Will start or restart the server after setup.
Running Will ensure the server is running after setup.
Stopping Will stop the server after setup.
Stopped Stops the server before applying Mail and New Realm changes.
