First off, I jumped on to our server and dumped everyone's spam folders. I made sure that spam was the only thing in the spam folder before I dumped what was in them. Now for the next 24 hours I am going to monitor the amount of spam that hits the spam folders (which I would say accounts for 90% to 95% of all spam). I am also going to watch the amount of messages that are a false-positive (not really spam, but get sent to the spam folder), and how many messages still hit the spam folder even if the sender is whitelisted.
When a user is whitelisted, in theory, there message should pass right on to the user's inbox no matter if the server thinks the message is spam. How ever, in practice, sometimes this fails on some messages. I am not sure why some whitelisted emails do not get thru and instead get put in the spam folder, but that is an issue I need to work with my ISP on.
So yes, really this is just me being a nerd. I mean really there is no use for this data except to have a ball-park figure of how much I have cut end user spam levels. But that is something I can put in my evaluation (if I ever get one) as something I did. It really looks good if I can put something like "Cut end-user spam levels by 90%" or what ever percent I am able to cut it. LOL. Also over the next month or so I am going to work with my ISP to fine tune the system so it is even better.
