huh? i see no evidence of that. the imap view of the remote folders 
didn't change, but that's expected (and `UseNamespace no` is pointless 
on that side, as the server uses no namespace to start with).

yeah, that's why it's saying that the namespace is "INBOX.".
the implication is that you can't make a 1:1 copy, as the target server 
just won't have it (with its current configuration).
you can limit Patterns to INBOX*, but that obviously implies data loss.
you can map everything into a subfolder on the target side, but that's 
obviously not 1:1, and you'd have to have the users re-organize it 
according to their liking.
