Description Nico Stöckigt univentionstaff 2017-12-04 12:36:47 CET
Since 2003 (IDNA2003; RFC 3490) special characters (like Umlauts) can be used in domain names. In 2008 (IDNA2008/IDNAbis; RFC 5890, RFC 5891, RFC 5892, RFC 5893, RFC 5894) the possibilities were even extended. By this a domain like 'rößlein.de' is possible.

In UCS/UMC you can create such a maildomain but when trying to create a users mail-address - the local part is without special chars - you'll receive an error saying: "invalid syntax".

I'm not sure if this is only an udm problem but from my point of view, openLDAP and bind9 are ok with IDN-domains. We should check postfix, samba/AD as well as udm so that UCS can handle these new abilities.

also in the DNS section, UDM has problems to create the zone.

There is somewhere a patch for this problem in another bug, which encodes the names in IDNA form.

I was referring to Bug #34948 - the patch is for the windows name, not for mail addresses.
Comment 6 Stefan Gohmann univentionstaff 2018-11-28 09:33:10 CET
It is a Feature Request. Currently, we don't support it.
Comment 7 Nico Stöckigt univentionstaff 2018-12-03 12:46:25 CET
Since IDN was introduced nearly 20 years ago - and IDN domains are used also by our customers - I absolutely do not see this as a feature request nowadays.

Comment 9 Christian Völker univentionstaff 2019-09-24 11:39:24 CEST
OX allows creating such mail domains and UCS then fails in using these domains with umlauts. See (private) screenshot.

Therefore, I consider this being a bug instead of a feature request.
