Why does a particular Webmail application load automatically?

This is because, at some point, you clicked the Enable AutoLoad link in the Secure Webmail Login interface.

To disable auto-loading, perform the following steps:

  1. Access cPanel's Webmail interface (Home >> Mail >> Webmail).
  2. Click Go to Secure Webmail Login.
  3. Click Stop before the timer counts down to 0 in the window.
  4. Click Disable AutoLoad to make certain that the Webmail client does not automatically load whenever you access the Secure Webmail Login interface.
