SpamSieve

SpamSieve is a sophisticated Bayesian spam filter for Mac email clients that integrates with Apple Mail, Thunderbird, and other mail applications to automatically classify and filter spam messages. It uses machine-learning algorithms to learn from user corrections and adapt to individual spam patterns over time. SpamSieve has been a long-standing, actively maintained solution for users who receive high email volumes and want more accurate filtering than their mail provider offers. The app is trusted by thousands of Mac users worldwide and has been recognized by Macworld as Software of the Year.</description> <parameter name="recommendation">SpamSieve now includes a native Apple Silicon build as part of its Universal Binary distribution. Users running an older Intel-only build under Rosetta should update to the latest version for noticeably better performance and more efficient battery usage on M-series Macs. The update is straightforward: visit the official C-Command website to download the latest version, and your existing settings, trained filters, and mail client integrations will carry over seamlessly.
