During the mid 1990s my college used exactly this scheme when assigning names to student systems on the school's dorm network. Each student was assigned a hostname of the form username.student.rose-hulman.edu where username would be your school assigned login name. And you'd be able to receive e-mail as username@rose-hulman.edu and username@student.rose-hulman.edu.
There's supporting evidence of this dating back to 1993 saved in Google's USENET archives.
