His list must be set up with the default REPRO setting, which is that the
person sending the mail doesn't get a copy back (because he presumably
knows what it says).  If he (or any other subscriber) wants to see his
own messages, he should send the command
 
  SET listname REPRO
 
to the server (where "listname" should be the name of his list, natch).
