You mean all mailboxes under that?

Yeah, there's currently no way to restore entire hierarchy of mails,
you'd have to do it one mailbox at a time. Or .. hmm. there are some
pretty horrible workarounds though.. For example you could do:

dsync -o mail_location=mdbox:mdbox:/var/spool/imap/partition7/11/andre=sneakymustard.com:INDEX=/var/lib/imap/user/11/andre=sneakymustard.com:MAILBOXDIR=mailboxes/backup-1234 -u ..etc..

So basically override the default mail_location but only change the
mailboxes/ directory to mailboxes/backup-1234. I think that should work.
Take a backup first. :)
