Yes, postfixpolicyd can do this. The real trick is, as you point out, the quotas for local users. We had to install this here since our customers have some strange desire to send their username and password off to whoever asks for it despite being told multiple times that no one needs their password.... rate limiting them works, but does break some people who have (legit) mailing lists run off some strange homebrew mechanism. (Small businesses typically, the largest is the local arts movie theater with a monthly mailing of upcoming movies.) See http://www.policyd.org/ for details. Easy enough to install, tricky to tweak to be useful.
