Not using both sendmail servers.

FWIW: I have 3 registered domains -- all pointing to a single public IP on
my linux/iptables based firewall. My sendmail server sits behind this
firewall (in a DMZ) with a private IP address. I use iptables to port
forward tcp/25 to this dmz server. I just configure sendmail to handle
virtual domains so that all 3 domain names are considered local.
