I just noticed today that I am getting no new mail messages into my spam folder and I am getting a lot of previously marked spam in my inbox. I am running OS 10.14 and Version 2.9.34 of SpamSieve. I have checked the box in preferences to use SpamSieve. I get the SpamSieve Train as Spam in my pull down menu and when used it moves it into my Spam Folder. I checked the log file and didn’t know enough to tell what I found. I can enclose it if that helps.
