Below is the results of nslookups both ways. As you can see the
nslookup of mi-server.net does not include the proper IP, only Mr
Nasty's whoever it is that is taking all my email from me. What does
http://mi-server.net deiver on the outside world? I can't see it since
my own hosts file keeps me on my LAN.

C:\nslookup 83.104.235.34
Server:  cache-1.ns.demon.net
Address:  158.152.1.58

Name:    rbrennan.demon.co.uk
Address:  83.104.235.34


C:\nslookup mi-server.net
Server:  cache-1.ns.demon.net
