SpamArrow is a SpamAssassin based spam filter to effectively block any unwanted spam emails with near zero false positives. This anti spam software is a great add-on for Outlook and Outlook Express by automatically creating integrated spam-fighting toolbar buttons. Unlike most spam filter software products usually do, SpamArrow will never modify your original email message and never add message rules for Outlook or Outllok Express.

SpamAssassin is a powerful and smart set of filters that identify spam based on many characteristics. SpamAssassin is best (and usually) used on the server side. Thanks to SpamArrow, you can have SpamAssassin-class spam filtering in Outlook Express, without any effort. SpamArrow automatically moves all the spam it detects to a special folder named ‘SpamArrow’. Some features of Spam Arrow include :

• SpamArrow is a spam filtering plug-in for Outlook and Outlook Express.
• SpamArrow uses SpamAssassin based scoring content filters to identify spam.
• Mail determined to be spam is moved to a special " SpamArrow " folder automatically.
• You can train SpamArrow to use Bayesian statistics for even better accuracy.
• The filter threshold can be adjusted to be more or less aggressive.

Note:

Any incoming emails to the Inbox folder will be automatically checked by SpamArrow and the spam emails will be moved to the ‘SpamArrow’ folder. For any incoming emails redirected by the message rules to other folders, you need to use the ‘Action->Filter Current Folder’ toolbar menu to filter out spam emails. In another word, SpamArrow only "monitor" the Inbox folder and filter out the spam emails.
