What does "Connection Blocked" mean?

Situation The dashboard has a Connection Blocked stat, but it is not clear what that stat reflects.
Solution It is the % of connections blocked "at the door" by PDR etc. for the entire stack.


The value Connections Blocked is the % of connections blocked at the Essentials front door per Stack and the two sources we have for block list are Proofpoint Dynamic Reputation (PDR) and Cloudmark Sender Intelligence (CSI). Proofpoint Essentials utilises PDR & CSI for inbound email and IPs listed will block any message prior to delivery.
