copying Kmail filter

After having ended up with a total trashing of my updated Suse 9.1 due to a bad memory block and a harddisc problem I have installed a fresh Suse 9.1 on another partition. My /home is not damaged because I have it on a separate disc which does not seem to be affected. I want to use e.g. personal settings from my trashed instalation and are in most cases successful. I am stuck though at the Kmail filter settings. Neither a complete copy nor an edited kmailrc seems to work. Could somebody give me an idea how I can get back the filter settings which I have groomed over a long time?
