SpamSieve Technical Support

technical-supportKnown Issues

  1. SpamSieve 2.9.35 (released December 20) is compatible with macOS 10.7 through 10.14.5. After updating, see this page if you don’t see the SpamSieve commands in Apple Mail’s Message menu.
  2. macOS 10.14 has new data protection features that require the user to specifically grant applications such as SpamSieve access to do certain things. SpamSieve will automatically tell you what you need to do and when, but, in summary, you will want to grant SpamSieve Full Disk Access and enable SpamSieve’s plug-in in Mail’s preferences. If you have a “SpamSieve” rule in Mail but don’t enable the SpamSieve plug-in, Mail will apply the rule actions (moving all messages to the Spam mailbox) without consulting SpamSieve. This is further explained in the Security & Privacy Access and Enabling and Updating the Apple Mail Plug-In sections of the manual.
  3. If you are using Airmail on macOS 10.14, make sure that you have version 3.6.42 or later.
  4. If you are using Postbox with SpamSieve, please read this thread before updating to Postbox 6.
  5. If want to use a pre-release version of macOS or update to the latest release version as soon as it’s ready, check out the SpamSieve public beta.

  1. There’s lots of information in the SpamSieve manual, such as the list of supported mail programs and OS versions, setup instructions for the different mail programs, and a section on iPhone spam filtering.
  2. If you are using Apple Mail and SpamSieve does not seem to be filtering your mail, please check the Preferences ‣ Rules window in Mail and make sure that the SpamSieve rule is active (checked).
  3. For the best filtering accuracy, follow the instructions to do an initial training and to correct all the mistakes.
  4. Are lots of spam messages (or more than before) ending up in your inbox? Even if SpamSieve is catching some of your spam, there’s a good chance that there’s a setup problem. Just fix your settings, and the accuracy will return to normal.
  5. Wondering why you see spam in a Junk mailbox in addition to SpamSieve’s Spam mailbox? This is probably because of a server junk filter. Please see this page for more information about how this happens and how to cope with it.
  6. Have you checked the list of frequently asked questions, including the general ones for the application and the ones for Apple Mail?
  7. If your question is not answered above, please gather the proper background information and contact us by sending an e-mail to Please do not forward spam messages to this address.
