Knockout Spam is an easy to use self learning spam filter for Outlook. Our highly intelligent Bayesian spam filter can be more accurate than the time consuming ordeal of sorting your spam by hand. It easily integrates with Outlook so there are no new email programs you need to learn. KnockOut Spam transparently integrates into Outlook and works with any email account you check in Outlook; POP, IMAP, Exchange and webmail accounts like Hotmail. KnockOut Spam scans for email messages you have replied to and makes sure they will always make it to your Inbox. All addresses in your Outlook Contacts list will also be allowed into your Inbox. It also learns from good messages in your mail folders. KnockOut Spam comes trained with a library of several thousand spam messages, so it already knows what spam looks like. KnockOut Spam creates 2 new sub-folders in your Inbox named "Unsure" and "Spam". Messages it is unsure of will go to the "Unsure" folder. Messages considered spam will go to the "Spam" folder. If a message is miscategorized, simply "drag and drop" it into the folder it was meant to go to and KnockOut Spam will quickly correct itself on future messages. Power users can "right click" on a message to categorize it as "Spam" or "Good". You can also check a message's Bayesian rank and see why it was considered spam or not spam from the "right click" menu by selecting "Message Rank".
