Just today, SpamSieve has stopped moving all the items it marks as Spam to the Spam folder. It moves some of them (roughly half), but not all. I’ve changed nothing to my set up from when it was moving all messages to the spam folder.
It does color Spam messages appropriately, but it’s leaving them in my Inbox, as the screenshot shows.
I’m using Snow Leopard, Apple Mail (v 4.2), and I’ve just upgraded to SpamSieve 2.8.2 (from 2.8.1) to see if that would address this problem. It didn’t.
