User Groups
Groups are used in the Email Appliance to apply different message-filtering options to different sets of users. The user groups created here can be specified on the various pages of the Policy tab to determine which policy rules are applied for which users.
User groups can be selected from existing directory services groups or manually specified. Alternatively, you can manually create, modify, and delete user groups. You can enable alias support from directory services.
You can also enable alias support from directory services, view directory services alias maps, and enable and configure custom alias maps that allow messages to be redirected from one email address to another.
