Statistics
The following stats should give us an idea of how many incoming messages are being rejected. As greylisting is put into production, the amount of SPAM should decrease (Table #1). However, since users who forward email from other mail servers, or users on campus mailing lists will still receive SPAM, we also keep track of the change in % of accepted incoming messages.(Table #2)
When a server is added to greylisting the percentage might seem to increase because we're ONLY counting the server/addresses
that have been greylisted. That server is not counted in the stats prior to greylisting.
