+
+Occasionally it is necessary to send mail to someone on the net who is
+known only as the incumbent in an official position.  Often the mail is
+undeliverable because of employee turnover.  
+
+We have also had such a problem at NBS and have therefore created MAIL
+address synonyms such as SYSTEMS, MANAGEMENT, and LIAISON to ensure that
+mail is correctly delivered no matter who the incumbent happens to be.  
+
+I suggest that all systems which permit MAIL address synonyms install
+them.  I further suggest that the NIC or the ARPANet management select a
+standardized set of synonyms, thus increasing their utility.
