I have used spamsieve for years with great success. I now essentially has become worthless. I have marked emails as spam and they go to the spam folder but a message from the exact same address will show up in the inbox even though it had been marked as spam. What the heck is going on. Is something in Spamsieve corrupted somewhere. I’m using version 2.9.38 on a MacBook Pro with OS 10.15.2. Any ideas? Any help would be appreciated
Usually when people say this, either SpamSieve has been turned off in Mail’s Rules preferences, or the sender addresses are in your Contacts and you’ve told SpamSieve to always classify such messages as good. There is information on this page about how to diagnose such problems, or you could send in a diagnostic report.
