Yeah, but I work somewhere too of course, and although we don’t use Mailcow there, I can totally understand that you would prefer not to let users configure anything at all. Believe me, I’ve worked in IT support, I know the pain it can cause. 😉
But my impression is that the Mailcow developers have a very strong opinion on this topic, and I doubt you can make them change their mind. But feel free to open a feature request on GitHub, and I’ll upvote it. And that I mean completely unironically.
