sorry, bad news.
A short test confirms that this issue still exists in KDE4.4: 
I'm using the kubuntu-ppa packages at
http://ppa.launchpad.net/kubuntu-ppa/ppa/ubuntu 
kmail reports v1.13.0, kontact 4.4

copying one folder of ~1000 mails of ~318MB in total from one IMAPS server to
another IMAPS made memory consumption raise incredibly: 

top tells: 
beginning: VIRT=190M RES=73M
after: VIRT=2267M RES=1.4G 
memory is not freed after operation finishes.


btw: a first test with a folder with subfolders resulted in an segfault most
probably because one folder name includes a dot (root/a.b) which is the folder
separator on the destination imap server. This should be checked by kmail in
advance IMHO. Nevertheless some mails have been copied to a sub-sub-folder
(root/a/b) but not all.
