Syncing INBOX is a bit weak point with dsync currently. Basically the
problem is that the local and remote INBOX has a different mailbox GUID,
so dsync treats them as different mailboxes that have a naming conflict.
The usual way to resolve this by renaming doesn't work, because INBOX
can't be renamed.

You should be able to solve this by deleting the INBOX manually from the
other side and letting dsync create it again with the proper GUID. What
mailbox format do you use? I don't see mail_location in your settings.
