Norman, I guess I'm at a loss to exactly what you are trying to accomplish. Are you wanting to setup an email system that would allow only teachers to send mail to the students sub-mailbox folders? Possibly have only parents and students send mail to teachers sub-mailbox folders? Have the students i/o mail sent back to the teachers sub-mailbox folders? Maybe I'm seeing the trees and not the forest.
