Synching two IMAP folders with different Folder structure

[Christof Baumgärtner <offlineimap@xxxxxxxx>]

Hi,
I try to synch two IMAP folders. Folder 1 on server 1 is called "Test", 
folder 2 on server 2 is called "INBOX.Test".

Unfortunately offlineimap tries to create a new folder "Test" on server 1 
which fails.
This is part of my config:
---------
[Repository WebDe]
type = IMAP
remotehost = imap.web.de
ssl = no
# remoteport = 993
remoteuser = account1
remotepass = pass1
maxconnections = 1
holdconnectionopen = yes
folderfilter = lambda foldername: foldername in ['Test']
nametrans = lambda foldername: re.sub('^', 'INBOX\.', foldername)

[Repository Fastmail]
type = IMAP
remotehost = mail.messagingengine.com
ssl = no
remoteuser = account2
remotepass = pass2
nametrans = lambda foldername: re.sub('^INBOX\.', '', foldername)
folderfilter = lambda foldername: foldername in ['INBOX.Test']
-----------

Any ideas someone?

Thanks,
Christof
