I need to configure postfix to use individual sender quotas, and I can't yet figure out how. The idea is that, depending on the user logged in, he can send X number of mails this day. I'm currently using Ubuntu 10.04 server with Postfix+Dovecot+Mysql+Spamassassin. I've read that with some policy server you could do what I want, but can't find yet how. Anybody can throw any ideas how? Thanks!
