No login possible since Update to 2.30.0 ("NO Mailbox does not exist, or must be subscribed to")

[besca-red]

Describe the bug
Everything worked fine since the update of SnappyMail (2.30.0). Noone is able to login anymore. In the admin panel I can successfully test the connection with the same credentials that do not work on client side - all users return to SnappyMail's login screen after logging in.

To Reproduce
Steps to reproduce the behavior:

1. Start SnappyMail app in Nextcloud
2. Fill in credentials and log in
3. See log

Expected behavior
The login should be successful and the inbox should be shown.

Please complete the following information:

• Browser: Firefox and some Chromium based browsers
• PHP version: 8.1.26 (Ubuntu 20.04.6)
• IMAP daemon: Dovecot 1:2.3.7.2-1ubuntu3
• SnappyMail Version: 2.30.0
• Mode: Nextcloud 26.0.9.1

Is there a way to roll back to a previous version? 2.30 is working for some of my users but not all.
