Version 2.9.43 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:

• Worked around a bug in the forthcoming macOS 11.3 that could cause SpamSieve to crash at launch.
• Improved the following sections of the manual:
  • If Apple Mail Is Running Slowly
  • Resetting Mail’s Private Plug-Ins Folder
  • Security & Privacy Access
  • Setting Up Apple Mail
• The Use Growl global notification system checkbox is now shown as disabled when Growl is not available, e.g. on Apple Silicon Macs.
• Improved SpamSieve’s debug logging of messages received and processed.

SpamSieve 2.9.43 works with macOS 10.9 through 11.2.1 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.
