  • Internatinalized domain names (IDN) support

    Hi everybody,

    I have an OX installation reusing our existing email infrastructure (web hosting servers with courier for IMAP/POP3 and exim for SMTP).

    I'm trying to setup some IDN domains (like xn--cumpleaos-r6a.tk) in OX but have trouble logging in.
    If I understand the docs correctly, OX has IDN support and should send the login in punycode format, which is what we use in courier and exim, but in courier's log I see the login almost verbatim (demo@cumplea.os.tk) and it fails.

    The context has an lmapping for xn--cumpleaos-r6a.tk bot not for cumpleaņos.tk.

    I tried creating the users with punycode (demo@xn--cumpleaos-r6a.tk) and without (demo@cumpleaņos.tk) but that made no difference. I also tried with different --username, --email and --imaplogin combinations to no avail.

    Am I missconfiguring something? Is this a bug?

    Any pointers will be greatly appreciated.
