dsync error: Error: Can't delete mailbox INBOX: INBOX can't be deleted.

19 Sep 2014


      Hello,
I'm aware of these two threads
http://www.dovecot.org/pipermail/dovecot/2012-March/thread.html#134311
http://dovecot.org/pipermail/dovecot/2012-June/thread.html#136488
but unfortunately I wasn't successful with my dsync mailbox migration attempt despite the information I could find there. I'm using iRedMail setup for the dovecot server. I made sure that the dovecot mailbox for the mail import had been freshly created and untouched before I tried to run the following command.
Running this command:
sudo doveadm -vvv -o imapc_host=s04.srv-net.de -o imapc_user=username -o imapc_password=password -o mail_fsync=never -o mail_prefetch_count=20 -o imapc_features=rfc822.size -o imapc_features=fetch-headers -o imapc_port=993 -o imapc_ssl=imaps -o imapc_ssl_ca_dir=/etc/ssl -o imapc_ssl_verify=no -o imapc_features=rfc822.size  -o mailbox_list_index=no -D backup  -R -u michael@domain.com  imapc:
I get the following output (I took out some lines obviously not relevant):
