Version 2.9.49 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 12.5 and macOS 13 Ventura. We recommend updating SpamSieve before updating macOS. SpamSieve 2.9.49 should automatically update the installed version of its Apple Mail plug-in, and the plug-in should stay enabled. However, 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 to enable the plug-in.
• Made various changes to improve SpamSieve’s filtering accuracy.
• Updated the Outlook Filter Mailboxes helper app to work around a problem where macOS 12.3 would report an error at launch. It also now helps you figure out if Outlook Filter Mailboxes doesn’t have Automation access to control SpamSieve.
• Improved the following sections of the manual:
  • Does SpamSieve stop Web bugs?
  • Separate Spam Mailboxes for Each Account
  • Setting Up Apple Mail
  • Setting Up Outlook
  • Using a Spam Mailbox on the Server
  • Why do good messages keep going to the Junk or Spam mailbox?
• Worked around a macOS bug that could prevent a rules file written on macOS 12 on an M1 Mac from being properly read on macOS 10.15.
• Fixed a bug where certain Unicode character sequences in a message’s address list could cause SpamSieve to hang when matching against a rule list.
• Updated the Read Me.

SpamSieve 2.9.49 works with macOS 10.9 through macOS 13 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.
