In global settings there should be the info what is the current configuration. This info should be read from the config file.

In the tested system the config was using SMTP, but the SMTP info does not show up in the settings view.

Comments from the video chat today:

• default settings should be read from the pretix.cfg which is mounted RO into the pretix docker container
• changes/saved values should be saved to a different config file OR the database

A few issues and questions:

• does this work with read-only configuration file pretix.cfg?
• please fix conflict
• does this support setting the email per organizer/event, or only in the global config file?

Feedback during meeting

• does this work with read-only configuration file pretix.cfg?

Yes, it should be working.

• does this support setting the email per organizer/event, or only in the global config file?

Yes, it is implemented in that way, but needs further testing in real-world conditions.
