I gave you some incompleteinformation in my last post. I said that once you set a preferred webmail client in cPanel, you would no longer see the selection screen displaying all three webmail clients. That’s not exactly correct.
On the selection screen that appears after login at domain.com/webmail/ (where “domain.com is your cPanel domain), click the Enable AutoLoad link underneath your chosen webmail application. You will then select the number of seconds you want the system to wait before automatically loading your chosen client.
The next time you login, you’ll wait your chosen number of seconds for your webmail client to load. During that countdown, you can stop the AutoLoad (by clicking the Stop button) and select a different webmail client.
