Incoming mail should be queued by the sender until our mail service is back up again. Outgoing CS mail will not be available to Grad/Research Net users, but since CS Ugrads can send through the JHU mail server, CS Ugrads might still be able to send email during the services outage (just not from our lab computers or compute servers.)
