Norton AntiSpam works with any POP3 email program and automatically detects and flags spam as it arrives in your inbox and moves it into a special Spam folder, from where you can restore or delete any message. The program works directly on the TCP/IP level and does not reuqire you to change any settings in your email program. Norton AntiSpam can automatically learn from your email behaviour and will detect a high percentage of spam immediately after installation. You can also manually add new rules or add people to a never-block list to customize the spam filtering actions.
