Since some people got on my list and post commercial messages type MLM...
I decided to use the "OK" approval mechanism.
 
I still get messages but I am not approving them.
 
Question: Since one has to be a subscriber in order to place a message to
the list how can I find out who is sending those messages?
Ofcourse they don't reveal their real email address.
 
How can I match the information on the header with the names on the list?
