In trying to determine why a couple of my users did not receive emails that passed through our spam filter, I've ran into an issue where those email's deliveries FAILED because of 'Source: AGENT'
So now Im at the point of disabling all antispam agents on that server to help figure out which one is causing this. However right-clicking on the rules and selecting 'Disable" then restarting the Transport service does not actually disable the rules.
The GUI says the rules are all disabled, however get-transportagent still says every rule is enabled. And the test messages still fail delivery.
I've tried restarting the transport server, as well as the mail submission, information store, EdgeSync, Service Host, and still the rules stay Enabled.
Do I have to reboot the entire server before this bloody Rules will be disabled?
