Hi,
 	Today we have seven mx relays and each machine has the other six 
as peers. I often see 10-20 of these each second in my logs:
"
peer IP_for_apeer queue overflow (1024 entries), discarding new entry in 
"

Should we be syncing like this? Would it make more sense to limit peers to 
one or two hosts each and push updates in that way such:

Let each mx relay be labeled a, b, c, d, e, f, and g. Each relay would 
sync with the mx relays on the right hand side:

a -> b, c
b -> c, d
c -> d, e
d -> e, f
e -> f, g
f -> g, a
g -> a, b

Instead of how we do it today:
a -> b, c, d, e, f, g
b -> c, d, e, f, g, a
etc

Thanks!
Jonathan
