I had tried out Kontact a long long time, but then it was still highly alpha sort of code. Besides, I really hated that Kmail did not allow me to specify filter targets as IMAP folders. But all this was almost 2 years back, so today I thought I should give things another shot.
So I installed the latest kontact on Debian unstable. Kmail seems to have gotten around that problem by supporting disconnected IMAP, which is perfectly fine by me. The integration with aKgregator is really cool. The addressbook and calendar support looks sweet to.
It seems I’m going to be with kontact atleast on my home machine for a while now. Lets see when we can get a nice working groupware solution.
