If all users home directories are in the same place (e.g. /users/ac1,
/users/someone, /users/foo etc)   then you can do

		cd /users; mail *

At worst you might have to do this two or three times to get all users on the
whole system.  Remember that there will be a copy made of the message for EVERY
user you send it to - which could amount to a lot of disk space!
