Enabling an instance of Exim to run on different ports (26 or 587)

Expertise level: Easy 

The "Service Manager" section in WHM allows you to enable or disable services on your server. A disabled service will never be active on the server until it is re-enabled from the "Service Manager".

This Is also where you can activate an instance of Exim on a different port, such as 26 or 587.

Please follow this procedure:

1. Log on to your WHM as root.
2. Go to "Service Configuration" section.
3. Click on "Service Manager" icon.
4. All the services available will be listed here. To enable or disable the service, you can use the first check-box on the left side of each of the service listed.
5. Enable the instance of Exim here.
6. Click on "Save".
