The owner of UREP-L is moving the list to two other sites which will run
peered lists. During the interim, there are three peers: BNLVMXA (the
original home), PSUVM, and IRLEARN. All subscribe each other with the magic
name of "Peer distrubution list". When the owner does a review to BNLVMXA,
BNL also sends the command to PSUVM and IRLEARN. Fine so far. HOWEVER,
PSUVM then forwards the command to IRELARN also. How can we prevent this?
