I don't know how to configure the additional zimbra mta in Redhat 5.

First, I have installed the whole packages of zcs in redhat 5 in computer1. No Error, I can create user to send and to recevied mail. The hostname is mail.inter.com

then, in computer2, I have installed the second zimbra mta in redhat 5. No error.
The hostname is mta-1.inter.com

however, when I login to (https://mail.inter.com:7071) administrative console in computer1. The mail.inter.com is running ok, but the "mta-1.inter.com is not running.

The point is how to configure and make it work ?

I am new to use ZCS, I can't found much information about configuration of additional zimbra mta. I really need help
