[CentOS] Sendmail forwarding external email sent to root

Three ideas come to mind:
1) announce a different public name than the local machine name.
A) EG: machine name:donttellanyone.theservername.com
public (DNS) name: www.theservername.com
B) Then set up virtusertable entry routing
root at donttellanyone.theservername.come to your email address.
C) edit /etc/aliases so that "root: | /dev/null "
2) start using greylisting! Milter-greylist works well w/sendmail for light-
medium load machines. =)
3) Turn off inbound email on port 25, if you can.
