Zimbra Desktop is a personal information manager roughly similar to Evolution. Considering the under developed state of Linux email clients it is worth a look. It is a java application that runs well in most environments but only comes in a 32-bit version. The current owner seems opposed to supporting a 64-bit version and it doesn’t install in 64-bit openSuse without a minor configuration adjustment. Open Yast and go to Software Management. Select View -> Patterns. Scroll down to the bottom and activate x86 Runtime Environment.

Download the file.
Extract to a temporary folder
cd to folder with the install.pl file.
sudo ./install.pl
