I created now a separate instance with a modified configuration file
with no auto=subscribe (or create), no replication and an empty storage.
doveadm config -n is attached.
Unfortunately the result is identical to my previous tries:
doveadm -o namespace/subs/location=mbox:/var/dovecot/subs -o
imapc_user='someuser' -o imapc_password='secret' -D backup -n
INBOX/ -R
-u someuser at somedomain imapc: 2>&1 | tee /tmp/doveadm-backup.log
Nov 03 09:06:35 dsync(someuser at somedomain): Warning: Mailbox changes
caused a desync. You may want to run dsync again: Remote lost mailbox
GUID c92f64f79f0d1ed01e6d5b314f04886c (maybe it was just deleted?)
doveadm mailbox status -u someuser at somedomain all INBOX
INBOX messages=0 recent=0 uidnext=1 uidvalidity=1577952633 unseen=0
highestmodseq=1 vsize=0 guid=c92f64f79f0d1ed01e6d5b314f04886c
firstsaved=never
Any ideas what else to try or how to debug that further?
I can send you the full log to your personal address, if that helps ...
