Well, you are struggling already almost 3 months with kmail and things
seem to get worse and worse.
Scrap your head, take a day off kmail and then look for a better
mail-program. T-Bird for sure is not a prime equivalent and then IMAP
on top with your tremendous bunch of mails.
I'd advise you to thoroughly study what Claws Mail has to offer and how
it looks and feels with all the mail stored on your own PC, no IMAP.
In the now 3 years, that I have kicked kmail into the wastebin and run
CM, there never was even a minor flaw. 
Regards.
