Set Up Smarthost
There are multiple ways to set up a smarthost in a Microsoft Exchange 2000/2003
multi-server environment. For a comparison of the two, see “Choose Smarthost
Method” on page 56.
Option One: Configure a Virtual Server
To filter outbound internet mail while still allowing internal mail to flow properly
between the servers and routing groups, configure each bridgehead server to use
an SMTP virtual server to deliver outbound mail to the email security service by
smarthost.
The steps below describe how to add the email security service as the smarthost
for external outbound mail without interrupting internal communication for internal
mail flow.
In most cases, you will need to add a new SMTP virtual server, even if one is
already in use. Bind this new virtual server to a different IP address or port
number to avoid interfering with the existing one.
Create a new SMTP virtual server
1. Click Start -> Programs -> Microsoft Exchange -> System Manager
2. Expand the top level -> Servers -> -> Protocols -> SMTP
3. Right-click SMTP and select Add a New Virtual Server.
4. Accept all default configurations on the SMTP Virtual Server screens.
Note: You will see an error message that the Virtual Server is configured to
use the same IP address and port as the existing server. Dismiss the error
message.
