Replication CRC error

[Artyom Aleksandrov]

Hi,

When using the “-A” flag (sync all users) no non-user mailboxes are synced.
As the man page imapd.conf(5) notes, ”... this could be considered a bug
and maybe it should do those mailboxes independently.”
Source: https://cyrusimap.org/imap/admin/sop/replication.html

But how in this case restore replication for shared folders? Run sync for
each folder separately?
