Sorry to jump into this topic, but can I ask why? Is dict quota is superior over Maildir++ quota in performance in general or it is "only" about the fact, that it's better in the case like above: activating the quota for many users later than the creation of the server itself? The question is interesting for me as well, as I need to implement quota with maildir (on NFS).
