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.
Mirapoint Source Server
- OK server.name Mirapoint IMAP4 3.8.3-GA server ready 1 LOGIN test@test.com test 1 OK User logged in 2 NAMESPACE
- NAMESPACE (("INBOX." ".")) (("user." ".")) (("" ".")) 2 OK Completed 3 LIST "" *
- LIST () "." "INBOX"
- LIST () "." "INBOX.Draft"
- LIST () "." "INBOX.Sent"
- LIST () "." "INBOX.Trash" 3 OK Completed
Running Dsync

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.
