Spam Buster is an anti-spam filter that works directly on your POP3 account(s) and marks spam messages, so they can be deleted before you download your mail with your regular email program. It uses a configurable set of keyword filters based on subject,sender, header and other email criteria. The program comes pre-configured with a large list of filters, and you can add your own or remove the filters that dont apply to your email habits. In addition, Spam Buster provides graphical statistics for top spammers, spam traffic by day of week, hour and more. It can also check mail automatically and notify you of new mail on the server.
