We have a windows mailserver that relays its outbound to a fbsd
gateway. We changed to a different fbsd gateway running 4.10. Windows then
began having trouble sending to 4.10. Windows netstat -an shows dozens
of lines like this:

Just off the top of my head...
You mentioned the freebsd machine is the gateway. Do you have a firewall
on the host blocking connections from the windows machine?
a forgotten detail is that the windows machine sends just fine to the 4.10
gateway for a few minutes, but the time_wait inevitably
No, it doesn't. I can successfully perform a whois from here on your domain,

When a person does a dns lookup to the server and its not already cached,
how does It find out the correct name server to use to find the ip?
The DNS navigates the DNS namespace until it finds a positive or negative
answer, or the until DNS's that should have the answer fail to respond.
