We currently run three load balanced outbound postfix servers and need to integrate a policy service that can track messages per hour for SASL users. We hope to have a service that can be cluster aware, or know how many cumulative messages have been sent by all the servers in the cluster per user per hour. Looking for some feedback from the community on your experiences with Postfwd and Policyd, or any other postfix policy servers that you have used.
Thanks in advance.
