Removing deleted emails from the trash folder on Mac Mail
I've set Mailbox Behaviors to erase deleted messages when quitting Email - that doesn't work - if I quit email, then open it again, they're still there. I even restarted my Mac but the emails still weren't deleted. Previouosly I had the setting as delete messages after one month and that seems to work, but now I want them deleted when I close Mac Mail I'm on High Sierrra 10.13.6??
