rsh does not return the status of the command that it executed on the
other machine.  There is nothing you can do to change that, however 
you have two other options.  

	1. Use the following:

		rsh csgrad "if mail -e; then echo you have mail; else \
				 echo no mail; fi"
	2. have csgrad forward the mail to your current machine so that
	yout don't have to worry about checking the mail somewhere else
