Although I don't want to make all my access through IMAP (mainly for 
performance and reliability reasons) I realised that there is a much easier 
solution than implementing Kmail's format in dovecot.  I just create 
softlinks from the dovecot directory to the Kmail directories to make them 
look like Maildir++.  This allows dovecot to export them to other clients.

I have created a shell script which goes through a Kmail folder store and 
creates all the softlinks.  It handles both maildir and mbox format folders 
(as dovecot cannot handle both formats in one namespace the script puts the 
maildir folders in the main dovecot directory tree and the mbox folders in 
a .../mbox subtree).

The script is available at http://www.cobb.uk.net/imap-export.  It is designed 
to be invoked as something like:

  imap-export ~/Mail ~/dovecot

and it assumes the dovecot configuration includes something like:

namespace private {
 separator = /
 prefix =
 location = maildir:~/dovecot
 inbox = no
 hidden = no
}
namespace private {
 separator = /
 prefix = mbox/
 location = mbox:~/dovecot/mbox
 inbox = no
 hidden = no
}
