[Dovecot] doveadm mailbox status - getting the size in bytes

Hi,

doveadm has an option to get the "vsize" of mailboxes, which is calculated by counting the number of linefeeds, but there does not appear to be way to simply get the size in bytes of a mailbox. I was wondering if there is something I am missing (I am using mdbox), or if not is it possible to implement this.

Thanks
