I don't know. It also took a very long time for KDE 4.2.2's kmail to
synchronize with the IMAP server, but that version was responsive during
synchronizing.

However, today I deleted the contents of the ~/.kde4/share/apps/kmail/dimap
folder, and I ran a script on the Courier IMAP server (Maildir based), which:

-Deleted duplicate messages
-Extracted the date information from every message's Date: header field and:
  -Renamed the file containing the message. The new names begin with the
seconds from 1970-01-01 00:00:00 until Date
  -Changed the file's MTIME for the same date
-By moving the messages to newly created cur directories, it:
  -Adjusted the files' CTIME order to the MTIME order
  -The files are even created in the dorectory with this same order
  -Sizes of the directory files are decreased if possible


I don't know if emptying the local dimap or cleaning up the server's maildirs
helped, but this process made kmail much faster and responsive.
