#Domains: Support IDNs in Email Hosting

[gtandersen]

Is your feature request related to a problem? Please describe.

Runbox 6 currently does not support internationalized domain names (IDN) on the Email Hosting page.

It is however possible to translate such a domain name, e.g. blåbærsyltetøy.no, to Punycode and then insert it.

Describe the solution you'd like

The Email Hosting page could translate IDNs to Punycode and then insert the result into the database.

Similarly, existing Punycode IDNs in the database could be translated to their IDN equivalents for proper display in the user interface.
