I am using Mac Mail on macOS Catalina 10.15.4. SpamSieve 2.9.39.
I recently did a complete reset on my SpamSieve filters because I had some mail that SpamSieve just wouldn’t learn was “good.” I have completely disabled the spam filtering at my mail provider.
I have marked every message from @space.com (NASA’s feed) as good, but SpamSieve refuses to believe that. I get regular messages from @onlyinyourstate.com, and they are always passed through…until today when one of three was flagged by SpamSieve as spam.
Yet, spam telling me how I can “perfect blood sugar by eating just this one food” isn’t caught?
Resetting SpamSieve should be the last restart, after you’ve looked at other possible causes for good messages going to the Spam mailbox and are sure that SpamSieve is doing this, and doing it because of the training. Please send in a diagnostic report and I can look at whether/why SpamSieve is classifying the messages this way.
Thanks for the report. It looks like Apple Mail is not set up to filter any messages through SpamSieve. So that explains why the spam isn’t being caught. Please see Step 4 here for how to set up the SpamSieve rule.
I don’t see any rules or junk filtering in Mail that move messages to the spam mailbox, so (if there is no other computer) the good messages must be being caught by a server filter.
