Topic: German umlauts and special chars in the domain name

==== Required information ====

Hello!
We use iRedMail and iRedAdmin-Pro for some time now.

Today we received the request from a customer to add a domain with non-english chars like the german umlauts äüö.
Unfortunately iRedAdmin complains about the domain name to be invalid.
We tried the international coding like "xn--autognstig24-hlb.de" but we don't know if this will work or not.

Zhang or maybe others, please advise what to do in this case.
Maybe it should be possible to configure the domains with their full and complete name, including the chars, and then internally convert them to the corresponding transciption.

Best regards,
Bernhard

Expected error. iRedAdmin-Pro restricts domain name (and email addresses) to be English characters (and some symbols). Non-english characters are not supported in iRedAdmin-Pro.

Please check parameter "reDomain" in iRedAdmin-Pro directory: libs/iredutils.py. It's regular expression used to verify domain names. Maybe you can modify it to work with German umlauts.

P.S. Looks like below modification works, but i didn't test it with iRedAdmin-Pro:

# Original
#reDomain = r'''[\w\-][\w\-\.]*\.[a-z]{2,6}'''
reDomain = r'''[\w\W\d\D\-][\w\W\d\D\-\.]*\.[a-z]{2,6}'''

Testing in Python shell:

>>> reDomain = r'''[\w\W\d\D\-][\w\W\d\D\-\.]*\.[a-z]{2,6}'''
>>> r = re.compile(reDomain + '$', re.IGNORECASE)
>>> r.match('äüö.com')
<_sre.SRE_Match object at 0x106615850>                       # <- It works.

It doesn't work as you expect.

Re: German umlauts and special chars in the domain name

Hello Zhang,
thanks for the quick reply.
Adding the domain name works but then I get internal server errors when accessing the iRedAdmin-Pro page.
The apache log file says:

What can we do?

IMHO domain names with non-english characters will be coming more and more often.
This feature has to be implemented.
Please share your thoughts.

Best regards,

Bernhard

Re: German umlauts and special chars in the domain name

Well, many places in source code have to be improved to support non-ascii domain names. We have no plan to support it, sorry.
