I have tried to setup a domain containing an umlaut. Tried both unicode and punycode notation, similar to this older issue #446 . 
And just as described in the issue, the idna is always stored in punycode notation in the database, but displayed in unicode.

Whenever I try to send a mail, I get the following error:

![image](https://user-images.githubusercontent.com/1128084/89713358-8a315780-d997-11ea-9018-0f16acfdc64b.png)

I'm currently on Mailu 1.7, have already setup 4 other domains and can only guess it might be broken. Maybe someone else with umlauts or other special characters in their domain can say if its working for them and what I might be doing wrong, that would help a lot.
Umlauts not working on my site

Using the domain with the umlaut as an alternative does work when receiving mails and redirects them correctly to the main domain.

Hi There,

The `Mailu`-Project is currently in a bit of a bind! We are short on man-power, and we need to judge if it is possible for us to put in some work on this issue.

To help with that, we are currently trying to find out which issues are actively keeping users from using `Mailu`, which issues have someone who want to work on them — and which issues may be less important. These a less important ones could be discarded for the time being, until the project is in a more stable and regular state once again.

In order for us to better assess this, it would be helpful if you could put a **reaction on this post** (use the :smiley: icon to the top-right).
- 👍️ if you **need this** to be able to use Mailu. Ideally, you’d also be able to test this on your installation, and provide feedback …
- 🎉 if you find it a **nice bonus**, but no deal-breaker
- 🚀 if you want to **work on it yourself**!
We want to keep this **voting open for 2 weeks** from now, so please help out!

@username_0  Thank you for posting the workaround. Are you willing to create a PR to add the workaround to the FAQ?

@username_0 I believe that a fix for this went in recently; can you reproduce the problem on https://test.mailu.io/admin/ ? (admin@test.mailu.io:letmein)
