I'm not a postfix user at the moment, but i've had mail and proxy
servers decide that info in /etc/hosts (or their own configs) is more
important than dns despite nsswitch.conf order.

I'm also attempting to telnet to port 25 of, and
getting 'Connection closed by remote host' from putty (no linux box on
that network)

So i'm guessing there are a couple of issues here.
