If I am looking at everything correctly all traffic coming into the system from the 82.0.0.0/8 network to port 25 on the mail server should be blocked.

What am I missing?

Maybe they are connecting to the MSP aka 587/tcp rather than port 25? It's hard to tell from your message which mailserver lines are from machines under your control; try editting the mail headers a little less and we might be able to do better.

Otherwise, maybe your firewall rules are not working, are applied to the wrong network interface, etc.
