Version 3.0.2 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, 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 3.0.2 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.

Apple Mail
  • Apple Mail: ExtensionsApple Mail filtering when using the Mail extension is much faster and is no longer limited by the number of messages in a mailbox.
    • Settings: Apple MailThis applies to the Check inboxes for new messages not sent to Mail extension, Filter spam messages in other mailboxes, and Add green flag to unread good messages features.
    • To enable fast filtering, make sure that you’ve granted SpamSieve Full Disk Access. SpamSieve will still work without it, but in some cases it will be slower or report an error if a mailbox contains too many messages. If you were previously using SpamSieve 2 with Apple Mail, it most likely still has Full Disk Access. Otherwise, or if it seems like filtering is slow, check System Settings ‣ Privacy & Security ‣ Full Disk Access to make sure SpamSieve is enabled there.
    • If you haven’t granted Full Disk Access, but SpamSieve thinks you would benefit from doing so, it will show a warning help link in the Settings ‣ Apple Mail ‣ Setup window.
    • Fast filtering currently requires macOS 13 Ventura or later. (On macOS 13 and earlier, it’s not really needed because the Mail plug-in is available.)
    • Settings: Apple Mail FilteringWhen fast filtering is available, SpamSieve now defaults to checking for new messages every 30 seconds instead of every minute. If you want, you can go to the Settings ‣ Apple Mail ‣ Filtering window and set it to check even more frequently, e.g. every 5 seconds, to minimize the time that spam messages spend in the inbox. In most cases, this doesn’t add much CPU overhead, however it might make Mail less responsive if you have a slow network connection or if Mail on your Mac takes a long time to fully download new messages for some other reason.
    • Settings: Select Apple Mail Mailboxes to FilterThe Select Mailboxes to Filter… sheet will no longer show large mailboxes in orange or red when fast filtering is available, because it’s now fine to select them.
  • The Mail extension no longer sets the background color at all on spam messages if coloring is off. This lets you set colors yourself for other purposes.
  • Improved the reporting of duplicate accounts when training from Apple Mail.
  • Clicking the Filter Now button will now filter the inboxes, too, not just the selected mailboxes.
  • SpamSieve will now log if Apple Mail is stuck reading a certain message.
  • Improved the error logging when listing Apple Mail mailboxes.
  • Added AppleMailMailboxListerExtraMailboxes to the esoteric preferences, which makes it possible to select mailboxes for filtering that Apple Mail failed to include in its mailbox listing.
Microsoft Outlook
  • Outlook: Training CommandsTraining an Outlook message as spam now removes the Good category.
  • Fixed a bug where SpamSieve would auto-launch when Outlook launched if Apple Mail filtering was enabled but Outlook filtering was disabled (and vice-versa).
  • Log WindowYou can now click on the Date column header to reverse the sort order in the Log window so that the most recent log entries are at the top. (For memory and performance reasons, Date is the only sortable column in the log.)
  • Settings: FiltersWhen opening the Log window, if no log entries are selected, it now auto-scrolls to show the most recent ones.
  • SpamSieve is better at reporting whether a server junk filter thought that a message was spam.
  • Improved the error log entry when SpamSieve lacks privacy access for the Use macOS Contacts feature.
  • BlocklistImproved the auto-creation of From (name) blocklist and allowlist rules so that SpamSieve learns more quickly when you train a message.
  • Settings: NotificationThe Uncertain spam messages notification is now disabled by default, as most people only want to be notified about good messages.
  • Fixed a bug where the training keyboard shortcuts didn’t work in Apple Mail or Outlook when using a Greek keyboard layout.
  • Work around a Core Data bug that could cause a crash when saving the corpus.
  • Updated the Danish, Dutch, French, Japanese, and Spanish localizations.
  • Fixed a crash that could occur when processing an e-mail message with an improperly encoded ZIP file attachment.
  • Fixed a crash that could occur when updating the Dock icon during a software update.

SpamSieve 3.0.2 works with macOS 10.13 through macOS 14 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.
