[Dovecot] Quota maildirsize and dbox

Hello,

Is there any reason that maildirsize Quota store should not work in dbox folders or any other folder based mailbox stores?

I have patched a test version here and it seems to work (added "dbox" check in src/plugins/quota/quota-maildir.c line 785).

If there could be any complications or unexpected consequences of this setup?

Thanks in advance luben
