Once you are confident that the server is well protected and set up properly, it is time to use WebMail. WebMail is great for when users are not in front of a computer owned by the organization. WebMail is built on the open source RoundCube project, and when configured appropriately, accessible from anywhere in the world. WebMail is automatically configured when the web service is started. For more information on the web service, see Chapter 5.

The actual setup of the web service can be oversimplified as being: Open the Server application (from /Applications), click on Web, and click the ON button (Figure 6-15).

Once On, click on the Mail service and check the box for Enable WebMail (Figure 6-16).
