Spam Blocker

I was getting 80 to 100 spam emails per day and could not get them to stop. I blocked them, unsubscribed, and marked them as phishing. Nothing worked until i got this product set up. I took about 3 days of learning and now i get NO spam. Incredible! You need to enter the IMAP address of the mail server you are using to start it up. Then you choose monitor, mark all the bad emails as spam, and select learn from the monitor. After a few days the spam starts going to your deleted folder. What a relief!
