dovecot - Nov 2018 - error Cached MIME parts don't match message during parsing: Cached header size mismatch (parts=)

I have a problem for specific mailbox. In mail.err file I see a lot:

I have many mailboxes on the server and each of them work perfectly except
this one.

Somehow cache files have been corrupted.

You can try to fix them with: doveadm force-resync -u user INBOX

Ok, I will try to do this but should I do some backup of INBOX earlier?
