Version 3.1.3 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 Junk mailbox. It’s quick and easy to control SpamSieve from within Apple Mail, Outlook, Airmail, MailMate, GyazMail, MailMaven, Mailsmith, 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.

SpamSieve 3.1.3 is a free update for those who have already purchased the SpamSieve 3.0 upgrade. If you’re using SpamSieve 2 and haven’t upgraded yet, the easiest way is to first let SpamSieve install the new version. At launch, it will show the Purchase window, and you can click the Check Upgrade Options button to get the upgrade discount without having to enter your old serial number.

The changes in this version are:

• Made various changes to improve SpamSieve’s filtering accuracy.
• The new MailMaven e-mail client from SmallCubed is now in public beta, and it includes built-in support for SpamSieve. The SpamSieve manual now includes sections for Setting Up MailMaven and Checking the MailMaven Setup, and these are linked from the Settings ‣ Other Clients window.
• SpamSieve is better at detecting whether a server junk filter classified a message as spam (for display in the Log and Corpus windows).
• Clicking a notification to open the message in SpamSieve’s Log window now works when SpamSieve isn’t already running.
• When using the Show number of new good messages in Dock option with the Apple Mail extension and the Check inboxes for new messages not sent to Mail extension option, the number shown in the Dock icon is now accurate even if the same message had been processed twice.
• Improved the efficiency of updating the rule hits statistics, reading settings, and various database operations.
• Improved the following sections of the manual:
  • Show Dock icon
  • Show number of new good messages in Dock
  • Turning Off New Outlook
  • Turning Off the Fastmail Spam Filter
  • Why are Apple Mail inbox messages not being processed?
• Improved the handling of AppleScript errors if you train a message when Apple Mail is overloaded.
• Worked around a bug where Apple Mail would ask the extension to filter messages that were drafts.
• Made further changes to prevent SpamSieve from triggering local network privacy prompts.
• SpamSieve will now report an error if it looks like filtering is being impacted by the Mac’s clock being wrong.
• Fixed a bug where SpamSieve could crash if there were errors reading Apple Mail’s database or if it contained invalid data.
• Fixed a bug where search fields weren’t appropriately cleared when stopping a search.
• Fixed a bug where the training toolbar buttons were enabled in the Words tab of the Corpus window.
• Changes to the esoteric preferences from Terminal now take effect right away.

SpamSieve 3.1.3 works with macOS 10.13 through macOS 15 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.
