Version 2.9.38 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:

• SpamSieve 2.9.38 (and also 2.9.37) are compatible with macOS 10.15, however a small number of customers are seeing issues with the Catalina version of Apple Mail. The latest information about Catalina is available here.
• Worked around an AppleScript bug in Apple Mail on macOS 10.15 that could result in messages trained as good being moved to the inbox of an account that’s disabled, making it look like the messages disappeared. This fix is available for all new installations and for older ones if you choose Install Apple Mail Plug-In from the SpamSieve menu. (If you weren’t seeing this problem or have no disabled accounts, it’s not necessary to update the plug-in.)
• Worked around an issue that could prevent some Apple Mail messages from being filtered through SpamSieve if SpamSieve had not yet launched and the Mac was overloaded, e.g. because it was relaunching all apps after logging in.
• Worked around a problem where SpamSieve could be slow to launch if the system privacy database was overloaded.
• Added the If the Apple Mail Plug-In Doesn’t Appear in the List or Doesn’t Stay Enabled section of the manual.
• Improved the following sections of the manual:
  • Enabling and Updating the Apple Mail Plug-In
  • How can I rebuild Apple Mail’s database?
  • Setting Up Apple Mail
  • Turning Off Microsoft Spam Filters
  • Why does a message disappear or go back to the spam mailbox after I train it as good?
• A macOS 10.15 bug can prevent Apple Mail messages from being moved to the Spam mailbox, leaving them colored as spam in the inbox. SpamSieve now offers an alternate Apple Mail Script Rule setup for the small number of customers affected by this bug.
• Added an experimental esoteric preference (click to enable/disable) to flag incoming spam messages as gray. A few customers are running into a Mail bug in macOS 10.15 that prevents rules from moving messages (even when using an Apple Mail Script Rule). This workaround makes it possible to set up a smart mailbox for gray flagged messages, so that they can easily be viewed and bulk-deleted even if the messages remain in the inbox.
• Worked around some bugs in macOS 10.15 that could cause Mail to hang when SpamSieve launched.
• If the Rules file is damaged, SpamSieve will now report some more information about the problem.
• The Apple Mail - Server Junk Mailbox script now has an option to only mark confirmed spam messages as read, leaving them in the server spam mailbox rather than moving them to a shared spam mailbox.
• Fixed a bug that could cause a crash when a Software Update… error occurred.
• Fixed a bug with the crash reporter window and Dark Mode.
• Modernized the localizations.

SpamSieve 2.9.38 works with macOS 10.7 through 10.15 and requires an e-mail client. Older versions are available for older operating systems.
