The Bayesweep add-in for Outlook and Outlook Express allows for simple and effective spam control directly from your inbox. Relying on existing examples of emails already in the inbox, Bayesweep provides personalised classification of spam and non-spam emails as decided by you. No continual downloads of new definition files or patches required. Furthermore, Bayesweep technology can help classify other types of emails according to business, personal and other relationships, making email prioritization easier than ever.
