I have computers running bind9 locally, so any reference to dnslookup is 
direct to another box on the same network with full details of the entire 
system, output restricted to local only. Other usernames and alias names not 
included in /etc/aliases are accepted.

root at rp35:/home/chrisbell# exim4 -bt webmaster
R: dnslookup for webmaster at rp35.lo3
webmaster at rp35.lo3 is undeliverable: Unrouteable address

My mail gateway and mail server together are rejecting large amounts of junk 
and relay attempts, with detailed logging by the gateway.
