offlineimap and local courier-imap

[Bjoern <bes@xxxxxxxxxxxxx>]

Hello, 
i want to use offlineimap with a local courier-imap server but have some
problems with the folder naming. I know the command from the documentation:

nametrans = lambda foldername: re.sub('^INBOX\.*', '.', foldername)

But it doesn't work.

I get a lot of error messages like:
imap: imapsplit() called with input: (\HasNoChildren) "." "INBOX.foo.bar"
imap: imapsplit() returning: ['(\\HasNoChildren)', '"."', '"INBOX.foo.bar"']
imap: imapsplit() called with input: \HasNoChildren
imap: imapsplit() returning: ['\\HasNoChildren']
imap: dequote() called with input: "INBOX.foo.bar"
imap: dequote() returning: INBOX.foo.bar
imap: dequote() called with input: INBOX.foo.bar

I think the problem is that i have a deeper folder structures, but how
can i make offlineimap work with this structures?

Or can you recommend another imap-server who doesn't need the '.' in
front of every folder name?

Thanks
Bjoern
