Postfix limit outgoing mails per day

[Hagforce]

Hi

Is there any way to make postfix limit the amount of outgoing email each client (user or ip) can send each day?

I have some problems where accounts are sometimes abused, and causing problems for the whole server.

Yes,

use policyd:

or postfix-policyd package in debian based distros (old version v1)

Cheers
