@IanStewart ...
When you go to your Canvas Inbox (which is not the same as e-mail, by the way), the default view is to show you all messages ... as indicated by the "All Courses" drop-down menu at the top left corner of the "Inbox" screen. If you click on this drop-down list, you will probably see "Favorite Courses" (those that you have starred on the "Courses" >> "All Courses" screen) and "More Courses". If you look at either of these, you can filter your view to see only the messages that have been sent to you for the specific courses in either of those folders. Unfortunately, I don't know of a way to change the default "All Courses" view to something else when you click on the "Inbox" folder.
