	A suggested fix would be to prompt the user "Changes were made to the 
disconnected IMAP cache.  Commit changes to IMAP server?" -> "Yes" "No" when 
exiting KMail.  Maybe also have an explanation of the consequences.  If "No" 
is clicked just exit.  If "Yes" is clicked show a bar indicating progress of 
updating the IMAP server.
	The purpose of "No" is for those situations when the person is not connected 
to the network and updating the server is not an option.  (It would be nice 
if possible connection to the server is checked automatically.)
	The purpose of "Yes" is to explicitly commit changes made in case the user 
forgets about them.  (I often check my mail CTRL-L one more time before 
exiting to synchronize the cache and the server.)

	An analogy to what Bastian described would be if floppy disk drives had no 
light on them:  Everyone knows "don't eject the floppy until the light goes 
off".  If you do then the files might not be updated correctly.  What KMail 
needs is something similar to the light on the floppy disk.

Thanks !
