MAIL


Connection topologies for mail routing
Typically, mail routing on the network occurs across a mix of hub-and-spoke and peer-to-peer connections. In a hub-and-spoke topology, mail traffic passes between a central hub server and multiple spoke servers; no mail is exchanged directly among the spokes. A hub-and-spoke topology is suited to handling a high volume of mail across a large organization. In a peer-to-peer topology, on the other hand, every server connects to every other server. A peer-to-peer topology is commonly used when connecting a small number of servers in a workgroup or department.
