Example: KS_RECIPIENTS=1
Version: 1.4 and above.
Notes: The username portion of a user's email address, i.e. the part before the '@' sign, must be present in the 'User name' field of their person document.
Notes: kSpam also adds 'kSpamAdministrators' to the list so that administrators can also see the denied messages, so be sure to create a group by that name before you implement this.
