Gmail already marked Spam coming to Inbox
Gmail marks some incoming emails (correctly) as Spam. But they have recently - in the past two or three weeks maybe - started appearing in my Mail Inbox as well as the Spam folder. They DON'T appear in Inbox when I access my Gmail via a web browser at gmail.com.
I have checked all the settings I can see in both Gmail and Apple Mail, and can't see how to turn this off, so that Spam stays in the Spam folder.
Any ideas, please?
