Limit outgoing mail (x mails per IP per month)

I am going to limit outgoing mail per IP per month. I tested with postfwd2, which it supposed to be quite nice, but it's conflicting with `pmgpolicy`.

What are other PMG users' setups to achieve this?

For outgoing traffic is supposed that pmgpolicy is not enabled at all, or at least you could disable it. Anyway you could decide to use postfwd you after pmgpolicy so traffic not blocked by pmgpolicy could be evaluated by postfwd.
