Kmail duplicate and ghost emails

[Ianseeks]

Hi

How does kmail determine that an email needs to be downloaded from your ISP? 
It doesn't mark the emails on the ISP as read after downloading them.

I've got a situation where most days, it downloads emails as duplicates from 
up to 2/3 weeks ago and they show as unread.  I can then mark them all as read 
and remove duplicates via the menu options, I also end up with a lot of ghost 
emails in the threads which are generally the duplicated ones which you cannot 
remove.

I have tried creating a new user but the same things happen.

The downloading of duplicate emails also occasionally happens on my personal 
account on a different login but i can remove them and i don't end up with 
ghost emails (well, not as yet).

For the last 2/3 weeks or so I have been getting "PIM Migration complete" 
messages almost on every start up.

Any ideas how i can repair things short of reinstalling the whole OS.

regards

Ian
