Roller Network Help - How To Configure Microsoft Exchange

The following example is provided for informational purposes only. We do not provide technical support for mail clients or officially support any specific mail client.

In this tutorial we will present some basic examples of using Microsoft Exchange with Roller Network mail services. These examples were created with SBS 2003 (Exchange 2003) in a domain called "LAB" with a server named "LAB-U25BR098MD7" acting as domain controller and Exchange server.


Changing the Incoming SMTP Port

If your ISP blocks incoming mail on port 25, you'll need to configure SMTP Redirection and use an alternate incoming port. This example shows how to configure your Exchange server to accept mail on port 2525, although you can use any port above 1024. For more information see Microsoft Support Article 274842.

Step 1

Open the Exchange System Manager. Locate your server under "Servers" and expand the "Protocols" folder. Click "SMTP", right-click on "Default SMTP Virtual Server" and choose "Properties".

Step 2

Under the properties window that appears, click on the "Advanced" button under the "General" tab.

Step 3

You will be presented with a list of ports; the "TCP Port" column indicates the port this virtual server will listen on for incoming mail. Select the entry you want to change and click the "Edit" button.

Step 4

Change the TCP port to the desired value. In this example, we are using port "2525".

You've successfully changed the incoming SMTP port for Exchange. Click "OK" to save your changes.


Changing the Outgoing SMTP Port

If you can't send mail using port 25 you may need to use a smart host and change the outgoing SMTP port to the submission port, port 587. This example shows how to configure your Exchange server to send outgoing mail on Port 587. This is typically only useful if you're connecting to a smart host; see Configuring a Smart Host for use with Outbound Mail. Also see Microsoft Support Article 274842 for more information.

Step 1

Open the Exchange System Manager. Locate your server under "Servers" and expand the "Protocols" folder. Click "SMTP", right-click on "Default SMTP Virtual Server" and choose "Properties".

Step 2

Under the properties window that appears click on the "Delivery" tab and then click the "Outbound connections" button.

Step 3

Change the TCP port to the desired value. In this example, we use the official SMTP submission port 587. Click OK to save your changes until you reach the Exchange System Manager. You will need to configure a smart host when using an alternate outgoing port; see Configuring a Smart Host for use with Outbound Mail to configure a smart host.


Disabling Non-Delivery Notifications

Exchange has a bad habit of accepting messages and generating non-delivery notifications separately. This behavior is prohibited when using our Outbound Mail service as a smart host for Exchange, so here's how to disable them. For more information see Microsoft Support Article 294757.

If you are using our service as a front-end to your Exchange server, we recommend configuring the mail domain so it only passes valid messages (through the valid user table and filters) to your Exchange server. When properly configured to only pass valid messages, Exchange will not send external non-delivery messages.

Step 1

Open the Exchange System Manager. Expand the "Global Settings" folder and select "Internet Message Formats". Right-click on "Default" and choose "Properties".

Step 2

Under the properties window that appears, click on the "Advanced" tab and uncheck the setting for "Allow non-delivery reports".

Click OK to save your changes.


Configuring a Smart Host for use with Outbound Mail

This example shows how to use our Outbound Mail service as a smart host for Exchange. If your ISP blocks port 25 you will also need to follow the steps under Changing the Outgoing SMTP Port. In this example, our Exchange server is handling mail for "lab.rollernet.us" and we've already added the Outbound Mail account called "@lab.rollernet.us". For in-depth information on configuring the SMTP connector see Microsoft Support Article 265293.

Step 1

Open the Exchange System Manager. Click on "Connectors" and locate your SMTP Connector. Right-click on the SMTP Connector and choose "Properties".

Step 2

Change the delivery setting to "Forward all mail through this connector to the following smart hosts". Enter our server IP address as "[208.79.240.5]" (square brackets are required).

Step 3

Click on the Advanced tab. Ensure that the settings on the Advanced tab match the ones shown below. Click on the "Outbound Security" button.

Step 4

The Outbound Security window will appear. Roller Network supports TLS encryption for submitted messages, so click on the "TLS encryption" checkbox to enable it in Exchange. Next, choose "Basic authentication" and click the "Modify" button. (Since we're using TLS the password won't really be sent in clear text.)

Step 5

Enter the Outbound Mail account name and password in the connection credentials window. The user entered here must match the one shown in our account control center.

Click OK to save your changes until you reach the Exchange System Manager. You've successfully configured a smart host in Exchange. (You might need to restart the Microsoft Exchange Routing Engine service and the SMTP service for these changes to take effect.)
