Yes, Michael was right - it works properly now. (I hope ;).

OK. I'll put it in the DAEMON section - this way I have only one point where all stuff related to imap is started.

Thank you for explanation. Regards,

Olaf

I think Michael's got this pretty much covered -- you need to disable the rolling replication for now, and then use sync_client -u (or if you're brave, sync_client -A) to get an initial sync of everything.  These two options work entire-user-at-a-time, so they should detect and fix the problems introduced by the partial rolling sync.

If you have mailboxes in a shared namespace (i.e. that are outside the user/ namespace), they won't be replicated by -u or -A.  You'll need to initially replicate those individually with sync_client -m.

Once you've got a complete initial sync done, you can use rolling replication to keep the replica up to date.  You can put the rolling 'sync_client -r' in the DAEMON section, so that Cyrus will restart it if it exits.  Or you could manage it from outside Cyrus, e.g. via systemd/initd if you prefer.

You cannot put sync_client in the SERVICES section.  The SERVICES section is for service processes (i.e. processes that listen on a socket and service client requests).  sync_client is a client, not a service.

Yes, at the beginning I was also thinking if initial sync is
necessary, but there was nothing in docs about it, something started
replicating and I simply assumed it does initial resync. I'll try it
this evening. :)

Since you use replication - are sieve scripts replicated as well?
There is -s option called sieve mode but it needs to specify which
users' files are to replicate and there is written that it is mostly
for debugging.

Yes, sieve scripts are replicated.

The way the rolling replication works is, that every time something is changed
on the master a "hint" is written in the sync log,

"MAILBOX user.foo.bar" indicates that the mailbox bar of the user foo
has changed
and the sync_client will sync this (and only this folder)
There are other "hints" e.g for changed subscription or changed sieve script.

But if the  sieve script is not changed sync_client in rolling replication
will not try to sync it. Using the -A or -u Option will sync the all/some
users, including all mailboxes, folder subscriptions and sieve scripts.

The -s option is only needed if you change a compiled sieve script so
that it is not logged in the replication log.
