I'm using this with a gmx account. I would assume this server is maintained.
I know nothing about UIDLs. Those duplicated emails cannot be displayed (i.e. 
when clicking on them nothing happens), they always stay  "unread" and I 
cannot delete them.

Is there something I can do to help ?
I can remember that building kmail/kdepim was quite some work...
Is there maybe some component which I could just try to build to do some 
debugging ?
(I don't even know where to start, kmail, pop3, akonadi, akonadi-agents)
Or can I use some tool to find out something about those duplicated emails ? 
akonadictl, mysql something, or akonadiconsole, something ?

Thanks
