I'm working on migrating IMAP users from Mirapoint Message Servers to Dovecot
servers. The Mirapoint IMAP server uses INBOX as a namespace for private
mailboxes. I created the same namespace in Dovecot, but when I migrate
mailboxes dsync seems to ignore/miss the namespace on Mirapoint and I end up
with all mailboxes under a INBOX.INBOX hierarchy.

I noticed that Mirapoint IMAP also advertises a third empty namespace and I was
wondering if this was causing it, but even if I explicitly set -n "INBOX." I
still have the same issue.
Below is my doveconf -n output:

Any help would be much appreciated.
