You could avoid this all by setting your outgoing smtp server to the
central server for everyone.

What you're asking for is completely illogical. The central server,
test.edu has local acocunts, bob, joe etc. and on the student.test.edu
server there are local accounts. You want the emails to always look
like they are addressed to usertest.edu which can't be achieved without
setting the mydestination on the student.test.edu machine to test.edu so
that it will keep the mails. You could however allow internal people to
send directly to userstudent.test.edu which would stay on the
student.test.edu machine, test.edu then would get forwarded on to your
central server.

Outside users would address their mails to studenttest.edu go to the
central server and then be forwarded on via your aliasing rules.

no maintenence, no muss.
