Disable Data collection consent

Is your feature request related to a problem? Please describe.

Hi and thanks everyone for your great work.

I'm currently switching from roundcube to your app, and want to parameter the app for my users.
I would like to switch off the data collection consent for everyone at once.
I don't see anything about it in the documentation. I tried to set occ config:app:set mail collect-data --value=False but it don't seems to work.

Describe the solution you'd like

As an admin, I woud like to switch off the Data collection consent at parameters level like I can do with the Classification by Importance.

Describe alternatives you've considered

I can occ user:setting $user collect-data false for each user but it's not really scalable.

Additional context

If you need more informations or anything, I'ld do my best to provide it to you !

Luclis.

Start by tracing how the collect-data user setting is read and how occ config:app:set mail collect-data --value=False and occ user:setting $user collect-data false are handled. The work is done when an administrator can disable data-collection consent globally through an app-level parameter, without changing each user's setting individually.
