You should not only preserve ownership and permissions but also hardlinks
to save space when using single instance store.

OK, you have set file ownership as shown above but what about permissions?
Check the permission of

/var/lib/imap/socket
/var/spool/imap/s/user/sp4rc/archive/cyrus.header

Note: if you installed via RPM you could check permission of the base
directories with rpm -V cyrus-imapd.

Make shure you set the permissions of all cyrus-imapd files correctly.
