Basic Messaging Architecture
Simplified Client Retrieval of MessagesIt is often desirable to be able to assign users to messaging servers, without needing to reconfigure clients. The Messaging Multiplexor can help achieve this, and is included with the Messaging Server 4.0 package.Messaging Multiplexor The messaging multiplexor is clever way of "hiding" the layout of your messaging servers from the end user clients, allowing assignment of users to messaging servers without having to configure the clients to the specific server. All clients point to the multiplexor for retrieving incoming messages. When a client connects to a multiplexor, the multiplexor does an LDAP
query of the Directory Server to find out which messaging server holds
the user's messages. It then connects the client to that server.
The multiplexor is essentially a proxy for IMAP4 and POP3 connections to
messaging servers.
