System settings control the functionality of Webmail Messenger.
There are various levels on which settings can be configured: factory settings, global settings, domain settings and user settings.
Most settings inherit their default value from a higher level. The global settings inherit the default values from the factory settings. The domain settings inherit from the global settings and the user settings inherit from the domain settings.
Factory settings ← Global settings ← Domain settings ← User settings.
Whether a setting is inherited or not depends on whether the associated “Inherit” checkbox for that setting is checked.
Not all settings are supported on all levels. Some settings are only available on the global level and some settings are only available on the user level.
In most setups, you only need to change the global settings. Webmail Messenger automatically adds user objects when required. Domains only need to be added if some setting must be changed for a complete domain.
