This undeliverable message thing that we get when we post to the
csound list seems to be generated by compuserve.  There is an unknown
address subscribed to the list.  Somehow, the compuserve mail server is
finding the original sender, not the list manager, and routing the message
back to the original poster.  I think it would be solved if the offending
address were unsubscribed from the csound list.  I think this may be the
address :  arl-img-5.compuserve.com
