Robust spam filter for major email clients.

Overview

SpamSieve is a robust spam filter for major email clients that uses powerful Bayesian spam filtering.

SpamSieve understands what your spam looks like in order to block it all, but also learns what your legitimate messages look like to avoid confusion. SpamSieve only marks spam in your email client so you never lose any mail.

The following is a partial list of SpamSieve’s features, so that you can quickly see what it can do and how it’s unique:

  • Powerful Bayesian spam filtering results in high accuracy and almost no false positives. It adapts to the mail that you receive to get even better with time. Some other e-mail programs include Bayesian filters, but SpamSieve is more accurate.
  • Integrates with your e-mail program for a superior user experience. Plus, you get the same great filtering if you ever switch e-mail programs or use more than one at a time.
  • SpamSieve works with any mail provider/host. It filters all your mail accounts. There is no extra charge for additional addresses or devices.
  • SpamSieve running on your Mac can keep the spam off your iPhone/iPad, and you can even train SpamSieve from afar.
  • Colors show how spammy each message is, so you can quickly focus on the borderline ones if you want to check SpamSieve’s work.
  • Integrates with the macOS Contacts app (and also Eudora’s and Entourage’s address books) so that messages from friends and colleagues are never marked as spam.
  • Automatically maintains a blocklist so that it can instantly adapt to spam messages sent from particular addresses, and catch 100% of them.
  • Automatically maintains a whitelist to guarantee that messages from particular senders or mailing lists are never marked as spam, without cluttering your address book with these addresses.
  • You can customize the whitelist and blocklist, adding sophisticated rules that match various message headers, or the message body. The rules can match text in a variety of ways, including using regular expressions.
  • Can use the Habeas Safelist, which indicates messages that are not spam, as well as the "ADV" subject tag indicating that a message is spam.
  • Many spammers encode the contents of their messages so that filters cannot see the incriminating words they contain. SpamSieve can decode and look inside these messages. Optionally it can mark them all as spam, on the theory that legitimate senders do not try to obscure their messages.
  • SpamSieve keeps track of how accurate it is, how many good and spam messages you receive, and how these numbers change over time.
  • Turn off new-mail notification in your e-mail program, and let SpamSieve notify you only when you receive non-spam messages.
  • The corpus window and log let you see how each spam message was caught.
  • Unlike server-based spam filtering services, your mail data stays on your own Mac, so your privacy is preserved.
  • SpamSieve supports AppleScript, so you can connect it to additional apps and fully integrate it into a custom workflow.

What's new in SpamSieve

Version 2.9.38:
  • 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:
  • 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.

Changed my life. Suddenly no more SPAM mails (>80 per day). Email is usable again. Amazing that there was no solution from Apple!

After linking to an insecure network overseas, I was getting a hundred or more spam messages every day, many of them offensive. With SpamsSieve, they're gone. You do need to follow the installation instructions precisely. And... do take the time to train the software to recognize your particular flow of spam. (It's all there is intro well-written but lengthy step-by-step instructions.) It's also important to monitor the Spam folder every day for the first couple of weeks or so to catch false positives and train SpanSieve to not delete a few specific email senders. (using version 2.9.36 - June 2019) You may need to switch your iPhone/iPad email from "Push" to "Fetch every 15 minutes" for new mail. That way, your Mac will discard the spam before it gets to your mobile device. The downside is that there can be as much as a 15-minute delay on your mobile device unless you go to settings and fetch manually when you're expecting an urgent email.

After training and having used for a few months now, it is currently almost faultless. Currently no false positives (identifying good email as spam), barely any false negatives - way, way better than Gmail or Ourlook. Because (by design) it runs locally on your main device, control and security are maximised, but it means it's a bit fiddly to set up and other devices may pick up spam if the main device hasn't processed the emails on the IMAP server. For that reason, would love a cloud-based version.

If you have a spam problem and most of us do SpamSieve will solve your problem. Takes a bit of time to train but the time and minimal effort is well worth it. I use it in Apple Mail and Airmail 3 and it performs very well. My spam stopped happening. Works just fine in Mojave.
