[Dovecot] DoveCot 2.0.9: Problem with some Clients and separator (migrate from Cyrus)

hi,

we had to move from a old dieing Sparc very quickly our Cyrus IMAP Users to Dovecot. Most things works, but some Clients (like Evolution or Thunderbird) are strange. Our separator in Dovecot2 is "^", the mailboxes on the filesystem are something like "INBOX.subfolder1.subfolder2", but in TB and Evo I see INBOX^subfolder1^subfolder^ In Roundcube Webmail, I have just a normal tree, as I expected.

I used cyrus2dovecot.pl for converting.

On Evolution I deleted the IMAP Profile and recreated it, and that was working, but it isn't a workaround for TB

So, how can I fix it?

namespace { type = private separator = ^ prefix = inbox = yes hidden = no subscriptions = yes }
