  The option REVIEW seems to be more "powerfull". You can set an Editor
  (wich is defined via the Editor= keyword) with the options REVIEW, and
  his/her messages with be send to the moderator. I tested this and it
  worked.

  What I meant here was a particular subdomain within the .nl
  here is is actually:
 
   Received: by pop.stud.let.ruu.nl id AA24238 (5.67b/IDA-1.5 for Multiple
                ^^^^^^^^^^^^^^^^^^^
        recipients of list ALBANIAN <[log in to unmask]>); Tue, 31

   The pop.stud.let.ruu.nl domain was the problematic one.
