There is no directive, but you can edit the resultant .cf file
and remove the line
C{E}root
or root from that line if more than one user.
Be warned, you _will_ break /etc/crontab and periodic scripts mail delivery.
The reason it needs to be exposed is probably these scripts because
other wise the from address for daily security scripts will be
root@<masquerade> rather than root@machine.domain. Now, it so happens
that most of these e-mails have the machine name in the subject or what not.
