Mac Mail Rule fails to execute for Junk mail
Most of my junk mail comes from stuff@gcardgrabber.com. It's all really worthless. So, I created a rule to move anything arriving from that address directly to trash. When I create the rule it asks if I want to apply it to existing mail, and it trashes all the mail from that address in the junk folder correctly. HOWEVER, Mail.app fails to apply that rule to newly arriving mail.
Why not? How can I get that rule to act on newly arriving mail correctly identified as junk?
