Choosing Which Messaging Server Components to Configure

When you install Messaging Server software, the installer installs all the Messaging Server packages. You then configure the appropriate Messaging Server component (MTA, Message Store, Webmail Server, 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.
