Is this happening for all students or just some? Is this using the new assignment module or the old 2.2 module?
Can you confirm that the 'Send notification' checkbox is ticked when the teacher is saving the grades and are they using the quick grading or the full 'Grade' screen?
I see 'Assignment notifications' and 'Assignment 2.2 notifications' as options on the message settings page - remember each students needs to check their own settings.
Cheers
