How do I run Roundcube in a test environment without it counting as an additional installation

If you're running Roundcube in a test environment.

Sometimes it's necessary to run Roundcube on a test server before you move it into production. Normally this test setup will also generate a different fingerprint and will be counted as an additional installation.

But there's a way to test safely without increasing your installation count: just log in to the Roundcube test installation using an email address containing the word 'demo'. For example, 'demo@yourdomain.com' or 'roundcube.demo@yourdomain.com'. Email addresses containing the word 'demo' won't trigger the increase of the installation count.

If your test environment has already generated a new fingerprint and blocked your downloads, just wait till the end of the day for the counter to be reset.
