You're making a wrong assumption here without testing it. If an IMAP 
client doesn't detect a file was removed from the server, it's broken. 
This works fine in the KDE Kolab client without leaving deleted messages 
on the server. If you really want to, look at the source code for the 
synchronization in the client. You can find this in 
kdenetwork/kmail/kmfoldercachedimap.cpp.
