Thank you for answer. Strange thing, because it is owned by vmail:vmail,
please take a look:
*drwxrwx--- 46 vmail vmail 4096 Aug 22 11:52 vmail*
I have /var/vmail directory binded to /var/vmail on secondary disk. Maybe
from some reason entry in /etc/fstab crashed? It happened after restart
server.

Honestly I am not sure that this was the reason of downloading emails
again. I am more sure that the first error "Permission denied" could do
this.
Do you know what could cause above error "Error: corrupted index cache
file" and how to fix it? It was happened suddenly without any changes in
dovecot configuration
