It works in the following way:
 
1. The server  which receives the original message from  the user decides
   whether or not acks are wanted.
 
2. All the other peers act as dictated by (1).
 
That is, each user  tells the peer it is subscribed to  what kind of acks
he  would like  to receive,  and doesn't  have to  bother with  the other
peers. Changing the  keywords on PURCCVM is pointless -  it is only doing
what UCHCECVM  tells it to  do. The users in  question should send  a SET
CHILE-L NOACK to LISTSERV@UCHCECVM (or, of  course, the list owner can do
it for them).
