Parallels Plesk Panel 11.5 with Horde 5 is installed on the server with CentOS 5 operating system.
National characters in mail messages are corrupted:
Horde 5.x requires libxml 2.7 to properly parse messages' content. If older version of libxml is installed, national characters are not interpreted properly.
Newer version of libxml (version 2.7) will be installed on the server automatically in future releases.
There are two possible workarounds to the problem:
Find a repository which provides libxml 2.7 and upgrade the package with
yum package manager:For example, you get them from this website:
# yum localinstall libxml2-2.7.6-1.3.i386.rpm libxml2-2.7.6-1.3.x86_64.rpm
Or configure yum to use some repository and then
# yum install libxml2
