Hello.
I have dovecot installation
# dovecot --version 20130205 (03a0af22100d+)
built with imapc backend.
I'm tried to sync mailboxes from another server after clean mail directory localy:
# dsync -v -o imapc_user="user@example.org" -o imapc_password="pass" -o imapc_host=imap.example.org -o imapc_features=rfc822.size -o mailbox_list_index=no backup -R -f -u "user@example.org" imapc:
and get this message
dsync(user@example.org): Error: Exporting mailbox INBOX failed: Backend doesn't support GUIDs, sync with header hashes instead
Repeated command returns this one message:
dsync(user@example.org): Error: Mailbox INBOX sync: mailbox_delete failed: INBOX can't be deleted.
What wrong with this build?
Maybe there is another way to do it? For example create backup in local temporary directory and synchronize this one and working storage.
