Sa4o - SafestMail4Outlook 2.0 Free Download

Permission based and Bayesian logic! Protect your e-mail against spam. Each user can have a unique way to define unwanted messages. During installation SafO imports all addresses from Received & Sent e-mails and also from Personal Contact Books. All these e-mail addresses are included in users whitelist so that future messages coming from those will be sent to the inbox. Messages from unknown senders will be sent to a quarantine folder and the sender will automatically receive an e-mail asking for a name and purpose of the message. Once answered, a pop up window will appear on the user's screen requesting his approval for that specific sender or message. It provides 9 filtering levels - SPF, sender's e-mail address, domain, subject, body content, header content, file attachment type, sender's country and bayesian method. Very intuitive. And now FREEWARE!
