• 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).

  • 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!

    Regards, Eric

    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.

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

    example.PNG

    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
    

    When sending a mail:

    this looks like unicode.
