The problem is that each of the peers should not be subscribed to
each of the other peers. Not only do you have a review loop, I see it as
a mailing loop also.
This is what it probably should be:
BNLVMA--- PSUVM --- IRLEARN
BNLVMA is subscribed to the list at PSUVM. BNLVMA's peer contains a
subscription only for PSUVM.
IRLEARN is also subscribed to the list at PSUVM. IRLEARN's peer contains
a subscription only for PSUVM.
If a review is sent to BNLVMA, BNLVMA forwards the request to PSUVM,
and PSUVM forwards the request to IRLEARN.
