Can't I trust that no mails with timestamp before I enabled compression
are uncompressed? Or will dovecot compress old messages keeping old
timestamp when copying messages between folders, or something like that?
I want to avoid reading every file to check if it's compressed
already, as that will add ages to an already slow process..

So,
find /var/vmail -type f -name "*,S=*:2*" -mtime +6 -exec gzip -S Z -6
'{}' +
Right ? I don't care too much if I miss on a few percent of the files..
(I'll probably have to use "-newer /somefile" instead of -mtime since it
will run for some days)
