We have added the ability to set-up a redirect to a certain webmail for your domain.

For example if your domain is domain.ext, then mail.domena.ext and webmail.domena.ext will be redirected to the webmail that you set. You can perform this setting under the E-mail tab, on the domain edit page.

If this setting is skipped, the standard functionality remains as before, that means a redirect to Horde IMP webmail will be executed.
