Bayes Anti-Spam
Anti Spam AddIn / Plugin for Outlook
For Outlook I had been using the SpamBayes plugin for years in order to remove spam e-mails. However, with Outlook 365 the addin stopped working for me. This reimplementation enables you to mark e-mails as spam or valid. Based on your input the addin learns how to classify e-mails. If the addin detects spam then it will move the e-mail to a configurable folder in Outlook. E-mails for which the decision is uncertain will be moved to another configurable folder. -
