mail send error

Eric

Hi,

All my sent mails like from user@name.be seems to been sent as from user@name. xn–be-2ca.
Something about IDN? There are no special characters in the name.

Ps:
While typing here i can see in the preview window that user@name. xn–be-2ca is automatically translated to the correct ‘user@name.be’. (i add an extra space to avoid it)

Anybody help?
Regards,
Eric

Hi @Eric,

what version of Kopano are you using?
Which backend?
Could it be that you accidentally included some unicode in your mail domain while creating the user?
What is the actual value that the mail is sent as (because user@name.xn–be-2ca gives “invalid punycode”, even with the space removed).

Eric

Hi @fbartels,

I am very sure I did not include unicode characters in my mail domain.
But i did some more tests:
Did over the same installation (core-10.0.6.270.b9af10c-Debian_9.0-amd64) -> same result.
Did over the installation on Debian 10 (core-10.0.6.223.e81f3b0-Debian_10-amd64) -> same result
Did over the same installation on Ubuntu 20.04 (core-10.0.6.298.8bbe34c-Ubuntu_20.04-amd64) -> all ok!

So it seems it is Debian installation related!

What about my other questions?

Which backend did you use (e.g. how did you create the user)?
what is the actual doman/tld? Or please give at least an example that produces valid punycode.

Eric

OK, I give another example:
john.doe@domain.com is translated to

and users are created with kopano-admin.

Hi @Eric,

I am unfortunately not able to reproduce this issue:

Created a user with:

root@kopano_server:/kopano/path# kopano-admin -c user1 -f "User admin cli" -e user1@kopano.demo -p user1
User created.
root@kopano_server:/kopano/path# dpkg -l | grep kopano-server-pa
ii  kopano-server-packages       10.0.6.298.677a125b5-0+178.1 all          Metapackage to install the entire Kopano Core stack
root@kopano_server:/kopano/path# cat /etc/debian_version 
10.4

@Eric
this looks like unicode.
