I too am having this exact same problem. It worked for me about a month ago, but has since stopped working. All of my Assignment settings are set up correctly as per the responses of others - emails are working for other things, so I assume that the SMTP side of things is set up correctly - it is just the email notification back to the student to say their work has been graded that is the not working.
Looking at other threads in this forum, it looks like many people have this problem, but there are very few solutions.
Any help would be gratefully received.
Thanks
