This is a difficult problem: - with aliases and virtual aliases, you don't know which quota to check unless you expand aliases during the smtp transaction. - since many messages may be received at small intervals, and delivery is not atomic (mail may be passed to a spam filter, ... etc). dealing with this is not easy in the general case. That said, a solution that "mostly works" may be good enough.
