I've noticed, that after removing a subfolder of a non-existant parent  
folder, the parent folder is not removed. Obviously this can only  
happen on IMAP servers that support sub-folders without parent  
folders, like Cyrus.
You can create a folder Foo.Bar which won't create folder Foo. If you  
then remove Bar, Foo keeps in the folder tree until you reload.
