dovecot - Mar 2021 - dsync error: Can't sync mailbox tmp: Mailbox isn't selectable

Hi,

I am trying to use dsync to migrate from mbox to Maildir with 

  dovecot --version
  2.2.27 ()


The configuration seems to be working and some of the mailbox can be mirrored
via

dsync -u username mirror  mbox:/home/username/mail:INBOX=/var/mail/username


I have trouble with one user where I get the error. 

dsync(username2): Error: Can't sync mailbox tmp: Mailbox isn't
selectable

Any ideas where to look for hints?

Regards

Hagen Bauer

Permissions seems obvious, but since tmp is a folder used by Maildir and you are
creating the maildir?

Maybe the user already has a mailbox named tmp and that is causing confusion in
the process?

Examining the existing mail folders for the user that is failing will probably
reveal something of interest. Be sure and check permissions though.
