As always, my suggestion is to simply copy the complete home directory to the 
new computer. Ideally, with `rsync -a ...` to ensure that all file properties 
are preserved. That's what I've been doing since decades and it has never 
failed me or caused trouble. After copying everything over, I simply started 
KMail on the new machine and everything was there.

Any other approach will almost certainly cost much more time and is certainly 
much more hassle than simply copying everything.

Ideally, you do the uploading to IMAP from the old computer. Then you don't 
have to bother with getting the old mail from the old computer to the new 
computer because all you have to do on the new computer is set up the IMAP 
account and grab a cup of coffee or tea or whatever while KMail downloads all 
old mails from the IMAP account to the new computer.

Important: When you do the uploading, either from the old or the new computer, 
use "copy". Do *not* use "move"! Using "copy" ensures that the old mail is 
still available locally even if the upload to IMAP failed.

I fully agree with Erik. It's amazing how creative people are. And I mean this 
in a good way. But trying to use dropbox with KMail is a sure way to shoot 
yourself in the foot.
