I think the likely approach here is in the forwarding. If I understand correctly, email sent to [EMAIL PROTECTED] is forwarded iff the from address is in a validity list (or hopefully/probably some other more sophisticated and stringent check). They could modify that forwarding mechanism to forward the email to all students iff the email is signed with a valid key. The end recipient doesn't have to know anything about the key.
