SpamSieve 2.8.4
C-Command Software has bumped SpamSieve to version 2.8.4. The updated spam filtering tool now integrates with Microsoft’s upcoming Outlook 2011 for Mac OS X and the new Thunderbird-based email client Postbox 2. SpamSieve 2.8.4 also boosts filtering accuracy, improves training in Apple Mail, and improves localizations, too. If you’re not a Gmail devotee, we agree with David Pogue and John Gruber that SpamSieve is the best way to keep your inbox clean on a Mac. ($30 new, free update, 7.8 MB)
