  • Plesk 9.2 for Linux/Unix


There is a domain with a full IDN name in Parallels Panel and with a mail account on it, for example mail@Bü

I cannot login to Webmail (Horde or AtMail) with full IDN name mail@Bü However login using Unicode name, e.g. works normally.


The Hotfix for Parallels Panel 9.2.1, 9.2.2 and 9.2.3 on Debian 4.0, 64bit is attached.

To install the fix download the file attached and unpack the archive, replace the existing file /usr/lib/courier-imap/authlib/authpsa with the fixed one and correct permissions. Please remember to backup the original file authpsa.You may use the following commands:

~# wget
~# unzip
~# mv /usr/lib/courier-imap/authlib/authpsa /usr/lib/courier-imap/authlib/authpsa.bak
~# mv authpsa /usr/lib/courier-imap/authlib/authpsa
~# chown root:root /usr/lib/courier-imap/authlib/authpsa
~# chmod 550 /usr/lib/courier-imap/authlib/authpsa
