You could connect to doveadm-server socket and basically ask the "doveadm 
quota" command via it. There's not much documentation about it though. But I'm 
sure I've mentioned details a couple of times in this mailing list..

I've also had some plans to make a somewhat easier socket for asking this. 
Maybe using doveadm-server process, or maybe a whole new quota-query binary 
that can talk multiple protocols.. It would be pretty easy to do, mainly I just 
haven't been sure what would be the cleanest way to implement this.
