How to verify proper working Edge 2013 sender reputation

In Technet Microsoft describes to verify the configuration of the sender reputation by “Get-SenderReputationConfig | Format-List ProxyServer*”
This not really mean that the sender reputation works proper.

How can I verify that the check is working at the server?
Will the reputation write a “added open proxy to IP blocklist” in the eventlogs?
Or into an other anti-spam log?
Will there be an comment in the SMTP logs for a problematic mail, “blocked by detected open proxy”?

Any further input would be helpfull
Thank you
