In one of the Internet Mail services I log in  the ordinary user can just
read all the mail sent to the root. Is the Root Mail box  is normally kept
like that other systems  or it was a configuration negligence by the systems
people ?

command  to read that mail to root is
when this command is given by the normal user 

cat  /var/mail/root

Then You can read all the mail send to the root .

Can somebody clarify ?
