Hello,

You need to provide the list of names to be included in the forwarding process - if you don't mind the list being hard-coded in the conf file, you may simply make put it as:

define SELECTED_USERS 'user1', 'user2',...

And then, add simple filtering, adding cause in a proper place:

Exec if $TargetUserName NOT IN %SELECTED_USERS% drop();

You might find some inspiration in im_msvistalog docs
