SpamSieve 3.3.2
September 18th, 2026 (SpamSieve)Version 3.3.2 of SpamSieve is now available. This is a free update for those who have already purchased the SpamSieve 3.0 upgrade.
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, MailMaven, GyazMail, 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.
The changes in this version are:
-
Microsoft has again changed its plans for the Mac version of Outlook:
Legacy Outlook had been scheduled to stop working on November 1, 2026. Microsoft now says that Legacy Outlook will continue to be available until October 2029. Some customers will no longer be able to connect to Exchange accounts starting in October 2026, but IMAP and POP accounts should continue to work.- Microsoft is reversing many years of public statements and no longer plans to bring AppleScript support to New Outlook. As a result, SpamSieve’s current direct integration with Outlook will end when Legacy Outlook is no longer available at the end of 2029. We hope that another method of integration will become possible before then.
For more information about this and about how you can continue filtering your mail with SpamSieve, please see the End of Support for Legacy Outlook section. -
When you move a message to the TrainSpam mailbox, after training the message SpamSieve now moves it to whichever custom location for trained spam messages you’d set (instead of always using Junk).
