The mailing list for listmasters using Sympa

[address@concealed]

I want to define 3 users  
(address@concealed,address@concealed,address@concealed) in my list who  
will the unique subscribers who will be able to sent to the list. The  
other mails (the rest of subscribers) sent to the list will be  
moderated. I made the following rules for "send-scenario":

##############################

title.gettext JUST-PROOF-RULES

is_subscriber([listname],'address@concealed') smtp,md5,smime  -> do_it
is_subscriber([listname],'address@concealed') smtp,md5,smime  -> do_it
is_subscriber([listname],'address@concealed') smtp,md5,smime  -> do_it
true()                             smtp,md5,smime  -> editorkey,quiet

##############################

I selected this file/rules through the "Who can send messages", but  
now all subscribers in my list can send messages.

Any suggestion???
