Solution: It might be that the spam tool you're using is slowing down Kmail. If you used Kmail tools menu to add a spam tool and added Spam Assassin (for example) then try another one. I noticed that bogofilter is much quicker. You'll need to remove the 1st one and add the 2nd. You'll then need to train the spam tool you just added (bogofilter): KMail Anti-Spam Tools
