Hi all.
I'm new to the list, and quite new to postfix. I'm running postfix 2.3 on one of my RHEL 5 servers, and have set up postfix to forward all emails to our Microsoft Exchange infrastructure. On the server running postfix, I have an applications that automatically generates emails. The issue I'm trying to solve is that at times, the application generates enormous amounts of emails, causing nearly a DoS attack on the Exchange servers. What I'd like to do is to have my postfix server rate limit the number of emails it's forwarding to the Exchange servers. For example, if I could get it to queue up emails, either on the inbound side or the outbound side, and forward them on a steady rate, that would be great. Note that all emails are generated locally on the server. Postfix seems to be a rather complex software, and I've not been able to identify which component I should be tuning to accomplish rate limiting. Any advice on this is greatly appreciated. Best regards, Kenneth
