Then the issue is that you are not correctly setting the  
authentication credentials for IMP.  By default, if using horde auth,  
IMP passes Horde's authentication credentials.  If dovecot requires  
the punycode representation of the username, then that is something  
you need to configure (i.e. via preauthenticate hook).

There's nothing for us to change.  Nothing is broken is Horde.

I am still confused why you think something is broken in Horde, when  
you admittedly have configured Horde to send the wrong authentication  
username to your IMAP backend?

We absolutely cannot assume that an IDN must be sent as punycode to  
the IMAP server.  As I have mentioned several times, the IMAP protocol  
does not limit authentication credentials to ASCII-only.  It is 100%  
backend dependent on what it is expecting.
