C-Command Software's powerful Bayesian email filtering tool SpamSieve [1] has been bumped to version 2.8.3. The update adjusts SpamSieve's tokenizer to make the spam filter even more accurate. In addition, SpamSieve now supports pre-release versions of Apple Mail, MailForge, and the upcoming Microsoft Outlook 2011. A few issues with installing the SpamSieve Apple Mail plug-in have been corrected, too. Full release notes [2] are available. ($30 new, free update, 7.1 MB)
