I see. this assumption differs from mine. I thought there is a group of pbsdb servers and a pop server stores pbs-data to only one pbsdb. i.e smtp server should ask almost all(half?) of them. Generally speaking, the number of pop accesses is very larger than smtp's. so I think every pop server would better to have pbsdb in himself. the number of queries from smtp server will grow but the network traffic can reduce. it depends on the pop and smtp access balances.
