[ale] limiting access to e-mail aliases

[jdebona at discom.net (Jon-Michael J. DeBona)]

Is it possible to place limits on who can use e-mail aliases?  We have
an alias that sends e-mail to every username on our system.  An unhappy
customer figured out that he could use it and express his worthless
thoughts about our service to everyone of our other customers.  We could
comment it out in the alias file and uncomment it everytime we wanted to
use it...(inconvenient)...or I guess send mail to everyone in a file. 
I've heard there is a way limit who can send mail to an alias though. 
(Sendmail 8.8.4)  TIA...
