I’m occasionally finding good messages that were originally in the Inbox that later end up in Junk with brown text on white. I use Gmail and have turned off it’s spam filter as described in 7.6.4 “Turning Off the Gmail Spam Filter”. I’ve also disabled Mail’s junk filter by unchecking “Enable junk mail filtering” on the Junk Mail:Junk Mail Behaviors tab.
In the most recent instance, the log for that message shows two entries: Predicted: Good(1) and Trained: Good (Auto), 7 minutes after the message was received.
I’m running SpamSieve 3.2.2 on macOS 15.7.3. I’m also running MailMaven Version 1.0.7 – build 7625, which is enabled to “Evaluate Arriving Messages Using SpamSieve”.
