InBoxer Anti-Spam Filter for Outlook - This award-winning, highly personalized, Outlook spam filter blocks spam while making sure you see the messages you need. Unlike most antispam products, InBoxer Anti-Spam Filter builds unique filters based on your mail folders using Bayesian and other advanced language-analysis techniques. No two installations are the same.You also may define trusted senders, companies, and even your entire contact list. InBoxer learns from mistakes and usually won't make the same mistake twice. It becomes smart enough to allow a newsletter about your favorite hobby, even if others might consider the message spam. It can even learn the difference between an intimate note from your spouse and offensive mail from a bulk mailer. InBoxer's design makes it tougher for spammers to beat. It's easy to install and never deletes a message. InBoxer does not work with Outlook Express.
