Version 2.9.41 of SpamSieve is now available.

Save time by adding powerful spam filtering to the e-mail client on your Mac. SpamSieve gives you back your inbox, using Bayesian spam filtering to provide amazing accuracy that’s constantly improving. SpamSieve learns and adapts to your mail, so it’s able to block nearly all the junk—without putting good messages in the spam mailbox. It’s quick and easy to control SpamSieve from within Apple Mail, Airmail, Entourage, MailMate, Mailsmith, Outlook, Postbox 5, PowerMail, and more.

SpamSieve running on your Mac can keep the spam off your iPhone/iPad, and you can even train SpamSieve from your iOS device.

SpamSieve protects your privacy. It does not need access to your mail account login and does not transmit your mail data anywhere. All the processing is done on your Mac.

This is a free update that includes the following changes:

• Added support for Apple Mail on the forthcoming macOS 11.1. We recommend updating SpamSieve before updating to macOS 11.1. In any case, if you don’t see the SpamSieve commands in Apple Mail’s Message menu, be sure to choose Install Apple Mail Plug-In from the SpamSieve menu and enable the plug-in.
• The Apple Mail installer is better able to detect when a new version of macOS requires a new version of SpamSieve.
• Apple Mail is faster at launching SpamSieve and more likely to find the right installed copy of it.
• Worked around a macOS 11 bug that prevented the diagnostic report from working properly on Apple Silicon Macs.
• Worked around a macOS 11 bug that could cause an Apple Mail hang when SpamSieve and Small Cubed MailSuite were both in use.
• Made various changes to try to work around a problem where Apple Mail training commands were intermittently not received on Macs with Apple Silicon.
• Improved the diagnostic report on macOS 11.
• Update the Korean localization.

SpamSieve 2.9.41 works with macOS 10.9 through 11.1 and requires an e-mail client. Older SpamSieve versions are available for older versions of macOS. In-depth information about SpamSieve is available in the manual.
