At my first programming job we had a solution for this. Everything generated by computer was filtered into a folder named for the application or mailing list that cause the email to be sent to us. My entire team did this. It meant that any truly important email from individuals or management ended up in our inbox instead of a folder. I had an additional filter set up so that anything labeled "high importance" was dropped into an "X-Important" folder. I would read those after I got bored reading the Marketing, Art Department and Support mailing lists.
