Kmail and filter messages


I recently reinstall my PC with OpenSuse 11.4 (x86_64).
I use a KDE and KMail (kmail-4.4.10-3.2.x86_64) for messaging.

I get quite a pub that I do not like SPAM, but I would like to automatically classify that important messages are not found drowned in the middle.

I use filtering rules, but I wish I could have more than 8 criteria by rule.
I saw that there were bugs open on the subject, but I do not know if this has been corrected.

Can you tell me if it’s fixed and if so from which version?
