On the file system there is no .mailing-lists.directory folder.

I repeated your step with the subfolder in drafts. Kmail does not create the 
.drafts.directory folder on the filesystem. Then I copied an email into the 
bla-folder (within kmail) just to see if the directory on the filesystem is 
created only when needed. But still there is no .drafts.direcotry folder in 
the filesystem.

For what I know akonadi stores metadata not the real data. However from what I 
see now I conclude this is not the case. So, is this an akonadi issue then?
