Use EST with DMZ and regular mailserver

Question / Problem

I have both a regular mail server and a mail server in the DMZ. How do I need to configure the Exchange Server Toolbox to work in this case?

Answer / Solution

In this case you will need two Exchange Server Toolbox installations, one for the DMZ mail server and one for the regular mail server.

Configuration for the DMZ Exchange Server Toolbox:

1. Install the Exchange Server Toolbox
2. Go to Settings | Installations and copy the fingerprint

Configuration for the regular Exchange Server Toolbox:

1. Install the Exchange Server Toolbox
2. Go to Settings | Installations and press "Configure as master installation"
3. In the new window, enter the host IP for the master installation. The DMZ installation needs to be able to reach the master installation using this IP
4. In the new table, add the DMZ installation as a client. You need to provide the fingerprint that you copied from the DMZ installation as well as an IP with which the master installation can reach the client installation
5. If you want client installation to use its own settings check the "Only share AD information" box. If you keep it unchecked, the master installation will share all of its (antivirus, rules, spam, etc) settings with the client installation

The client installation will now recieve AD information which it can use for processing. The master installation will always be the one responsible for maintaining the archive.
