@mmattel we have dropped one config setting - also the admin ui looks a bit different now ..... In addition the smtp encryption option is now either 'ssl/tls' or 'none' .... 'STARTTLS' has been dropped

Same as written in the code comment above, this is a release notes thing and needs mentioning there --> @pako81

Can one drop me a screenshot we can use for docs into: https://github.com/owncloud/docs-server/issues/1137 ? and clarify for which version this change is targeted?

@individual-it @phil-davis can I ask you for a quick look - THX a lot:

The failing case is that sendmail is set as the mode but no sendmail is installed/configured on the system (/usr/sbin/sendmail -bs). Looks like the exception is thrown but does not cause occ to return 1 as exit code

This can wait for merge until release-10.13.2 is out of the way, so we have time to discuss what happens for releases after doing this change for the PHP 7.4 code base - will it be "the usual" 10.14.0 minor version bump, and we work out how to address backward-compatibility issues (for example, that any real backward-compatibility issues can be handled OK for any apps that are affected).

Or would this cause a major version bump, forcing an 11.0.0 release that supports PHP 7.4...

From my understanding oc11 is php8.2 We can also merge this or into the php8.2 pr

I suppose this is blocked/stalled for now. Can't easily be part of 10.14 because of backward-compatibility issues that are not easily avoided.

I planned to do this as part of #40981 :shrug:
