Some more background information:

- Running 2.3.13 (89f716dc2)

- The rsync is run from the user's current mapped backend (from `doveadm
director status <user>`), in hopes to reduce NFS-related issues

- Kicking is done through one of the directors, to ensure all of the user's
connections are kicked.

Best regards,
Eirik

Btw, if your control files are OUTSIDE maildir and you are moving them  
back INSIDE maildir, notice (for example in my script) that .INBOX  
directory doesn't exists in maildir and control files for INBOX are  
placed directly in maildir instead. This is probably why you are  
failing to prevent resync/redownload.
