 That is a terrible idea, for two reasons:

  1.  You may be unnecessarily burdening uunet.uu.net
  2.  It is a hack partial solution at best.

 Your real problem is that you are using a version of 'sendmail' which
does not understand MX records.

 Solutions:
  Easy:- Find a host on your campus (Texas A & M ??) which can handle these
	 addresses, and set up you mail system to relay ALL outbound mail
	 through that host.  Obviously you must get permission first, and if
	 so, the admin of the relay system can probably help you with the
	 setup.

  General:-  Look in /usr/lib.  You will find there are two executables with
	 names that look like sendmail.  One is called 'sendmail' and
	 the other is called 'sendmail.mx'.  You will need to start using
	 the second one.

		cd /usr/lib
		mv sendmail sendmail.nomx
		ln sendmail.mx sendmail

	  Now do some tests on your 'sendmail.cf'.  As a result of the
	  different version the automatic definition of $w and $j may have
	  changed.  You will have to make the needed adjustments so that it
	  works correctly.

	  When you have it working, kill and restart the sendmail daemon.

	  (I do assume you have access to a nameserver).
