SpamButcher - Outlook Express Spam Blocker
Used as an Outlook Express spam blocker, SpamButcher can stop over 97% of spam immediately after installation. No training is required to get this high level of performance.
In addition to working as an Outlook Express spam blocker, SpamButcher can be used with most other email applications. The only requirement is that you access your email using the POP3 protocol.
You can configure SpamButcher to send scheduled summaries of spam it's blocked via email. Used with Outlook or as an Outlook Express spam blocker, accidentally intercepted email can be recovered by clicking on the message's subject in the report.
SpamButcher's spam filter uses the latest anti-spam technology to maximize the amount of spam caught, while minimizing the risk of false-positives.
