What does Last Action: "Traffic Mail" mean as my Traffic School status? (Los Angeles County)

I got a red light camera ticket - paid it and my status states Dismissed. However, as my first offense I was able to avoid the ticket being reported to the DMV only if I pay the fees and attend Traffic School. I took traffic school online and had confirmation that my certificate of completion was sent to the Van Nuys court house. When I went to check two weeks later, my ticket status read Last Action: "Traffic Mail." I am uncertain if "Traffic Mail" means they mailed me my permission to take traffic school - or that I have been cleared.
