  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.
