@kbudde I saw your project after I created this PR, maybe this PR can interest you.
If you have some time to test it, that would be great ❤️.

@kbudde do you have some time to test the PR?
Or maybe you know a Mail-in-a-Box user who can test it?

I create a PR only based on API doc, I need a user to test it because I know that documentation is not always accurate.

I see, I will test it at the weekend 😀

@ldez had suddenly some free minutes and tested some combinations. Works like a charm.

It's even possible to use a apikey instead of a password.
