Solved: Rainloop: How to access their Admin Panel?

[assistance_pls]

I just found this earlier post, so I will try it now.

Rainloop web-based e-mail client

I’ve read about Rainloop (another web-based e-mail client, link) before, but it was shot down because it wasn’t available for commercial parties that are using MAIB. It is however a very good webmail e-mail client, not as visually bulky as Roundcube. I saw that the basic version is available under the AGPLv3 license, which allows for commercial or non-personal use. So maybe it could be an alternative for Roundcube?

Go to the Owncloud admin page, there is a new option called Rainloop webmail.
Enable Automatically login with ownCloud user credentials
Login into the rainloop admin panel with the user admin and pass 12345
Add your e-mail domains and settings to your liking (change the admin login and password!)
Don’t forget to enable the Carddav server to be able to use your e-mail address book. The settings are done in the users own settings page.
You can now login with your username password at the normal Email app in Owncloud. You might happen to login/logout in owncloud to enable the ‘login with owncloud user credentials’.
