Moderation not working like documented?

Moin! I'm having little trouble with a list that ought to be moderated. The documentation of SmartList says: ------------------------------------------------------------ http://www.hartzler.net/smartlist/Manual.html#3f 3f.Moderated lists --------------- First create a file named "moderators", it should contain the fully qualified mail addresses of all the moderators for this list (i.e. just local usernames are not sufficient, at least include an @host or host! ). Then uncomment the appropriate "moderated_flag" line in rc.custom.
