SpamSieve on my new M1 MacBook Air isn’t working fully. It does correctly classify most real spam messages as such, but if it misses one or more, the ‘Train as Spam’ is funky. Sometimes it’ll correctly move a message when asked to do so and other times it will not. If there are 2 or more spam messages improperly classified as good, selecting two or more of them simultaneously, Train as Spam never works.
I have disabled the plug-in and re-enabled it. I have, of course, restarted the machine several times, all with no effect.
I also have a 2020 MacBook Pro with the exact same versions of MacOS (11.0.1) and SpamSieve (2.9.40). SpamSieve works perfectly on it.
