Setting up an IMAP Proxy

Before enabling the service, certain configuration steps are required. The service listener should be set to use port 143 and the normal IMAP service should be disabled. In addition, a user map must be selected in the clustering configuration settings to enable the proxy service to route connections.

Set up proxy routing information:

1. Log into the webadmin interface.

2. Go to the "Clustering" context and select "Clustering Setup" from the list.

3. On the "Routing and Authentication" tab, go to the "Routing" section.

4. Select the user map to use for the proxy services from the "User Map" drop-down list.

5. Enter the "IMAP request" fall-back IP and port values.

NOTE: These fall-back options are used if the proxy fails to match the incoming request information.

Configure the service:

6. Go to the "Clustering" context and select "IMAP Proxy" from the list.

7. In the "Listeners" section, click the "Edit" button next to the service listener.

8. Change the listener port from its current value to "143", and save the configuration using the "Save Configuration" button.

9. In the "Encryption and Authentication" section, enable the "Perform authentication on proxy" if you require it.

10. Click the "Save Configuration" button to make your settings permanent.

Enable the service:

11. In the "Services" context go to the "Services Management" page.

12. Click the "Stop" button next to the IMAP service, if it is enabled.

13. Click the "Start" or "Restart" button next to the IMAP Proxy service.
