Cloudmark Server Edition Online Help
Mail checking can be selectively enabled or disabled for existing users; see Selectively enabling and disabling spam checking. You can also set the default mail-checking option (either enabled or disabled) that will be applied to new users when they are added to the server, as explained below.
The General tab is displayed by default.
With this option selected, spam filtering will be enabled for each new user you add to the system. If you prefer to enable and disable spam filtering selectively, see Selectively enabling and disabling spam checking.
If you enable this option before the first time that you run CSE, all users are enabled for spam filtering.
