[Dovecot] is it possible to recover files from a dovecot.inboxe.cache file?

[Alfred Nutile]

I found this file in the mail boz and noticed it had 20 emails in it
(though you can only read really the header the body is cryptic cause
it is a bin file?)
Just not sure if I can and how to use this to restore the lost emails
in that inbox.
Thanks
