How does Knights E-Mail handle spam?
There are a number of ways to combat spam on the Windows Live platform. SmartScreen™ Technology learns to detect spam based on you reporting spam in your inbox. SenderID Framework matches the sender’s e-mail address to their IP address to protect against spoofing. About 95% of all spam and 99% of image-based spam is blocked. While spam traffic has increased 40% across the Internet, Microsoft has cut spam down 80% over the past year. If you use the web interface, all e-mail undergoes a virus check. However, since the anti-virus tools are server side, this does not apply if you use POP. See http://postmaster.live.com/ for more details.
