Looking for input from Kontact users

We're probably not too representative, running Kolab for only our family, but 
happy to oblige anyway.

All our kontact versions are 4.7.3. at the moment.

Platforms: Gentoo, Kubuntu and Windows. Total users: 5. The Windows users only 
use email, not the other Kolab functionality.

We also have two mobile clients, one nokia N900 and an android phone. On my 
N900 I use z-push for contacts/calendar and several mail clients: mostly the 
native client or claws mail, sometimes Kontact touch if I really need to use 
some Kolab specific function, e.g. accept an invitation.

At home, we have local home directories, although we do have a single mounted 
Documents folder for easy file transfer and central storage.

As of kontact 4.7.2 I'm quite pleased. Kontact hardly ever crashes on any 
platform, and basically everything works. I can honestly say we never lost any 
mail because of Kontact.

We started with Kolab 2.2.1, I believe, because I was curious to try out the 
shared addressbooks and calendars.

In earlier versions, more or less up to 4.6.x akonadi has been horrible, 
causing bad performance, crashes, calendars being unavailable/unwritable and a 
host of other issues. Our main requirement is email, and that has always 
worked, but it's been pretty bad in the past.

At the moment, we have only some issues with this bug: 
https://bugs.kde.org/show_bug.cgi?id=259949, which has to do with address 
autocompletion in kmail composer. Fortunately, this sort of works for us, so 
the bug doesn't hit us as hard as some other users (don't ask why...).

We don't use DIMAP at all anymore , but we have used the DIMAP/IMAP combo in 
the past, as that has long been the default setup. As far as I remember, it 
always worked, at least sort of, but I have deleted the whole local storage on 
a few occasions.

I think by now I would actually recommend moving to the latest KDE version 
including Akonadi for PIM data. I make no guarantees, but I think you should 
most definitely have a look into that. For sure, your DIMAP issues with the 
mounted drive will be gone, as Akonadi will take care of everything (mail + 

Good luck! Don't hesitate to ask for more info.
