Put it in /etc/hosts.
That _should_ work.
Note that part of the issue here is that Exim assumes it can resolve the
local hostname. "@" is Exim for "the hostname of the host that I'm
running on".
If you keep hitting DNS issues on the appliance, you might consider
something like dnsmasq -- it's a server designed to be very small, for
use on home routers where memory is tight. You can configure it with
appropriate dummy data.
(Note that /etc/hosts is not normally a good solution for DNS issues,
just a way to store up issues for later, but I tend to believe that
localhost and the hostname of the machine itself should be in
/etc/hosts, so that basic self-resolution can work without a network
connection).
