Choosing Which Messaging Server Components to Configure

When you install Messaging Server software, the Java Enterprise System installer installs all the Messaging Server packages. You then configure the appropriate Messaging Server component (MTA, Message Store, Messenger Express, MMP) on a Messaging host through the Messaging Server configuration program.

The following table shows which components you need to configure for each type of Messaging host.

Table 15–4 Which Messaging Server Components to Configure?


Type of Messaging Host Being Configured	Needs These Components Selected in the Configurator Program
MTA	Message Transfer Agent
Message Store (back end)	Message Transfer Agent, Message Store, Messenger Express Note: You need to configure the store for an MEM proxy after configuration is done.
Messenger Express (front end only, no store or SMTP function)	Messenger Express, Messaging Multiplexor Note: If you are only configuring Messenger Express, you must also select the Message Store and the MTA, or at least be able to point to an existing MTA.
Message Multiplexor (front end only, no store or SMTP function)	Messaging Multiplexor

Note –

Configuring the LMTP delivery mechanism requires configuration on both the MTAs and on the back-end stores. See Chapter 15, LMTP Delivery, in Sun Java System Messaging Server 6 2005Q4 Administration Guide for instructions on configuring LMTP.
