Creating IMAP folders/subfolders with Thunderbird

[Alex Regan]

Hi,

I have dovecot-2.2.15 on fedora21 with Thunderbird and having some 
difficulty creating subfolders and deleting folders.

Creating subfolders results in a folder at the root with a caret instead 
of a slash called folder^subfolder with an entry in .subscriptions with 
that name, instead of a new folder under the directory.

I'm also unable to delete any folders. The command from within 
Thunderbird is just completely ignored.

Any idea what's happening here?

Thanks,
Alex
