It's not listening externally (those are the IPv4 and IPv6 "localhost"
addresses).
You should configure your Exim install on NURSE to listen externally,
perhaps by commenting out "local_addresses" or running the appropriate
dpkg-reconfigure incantation for your installation (you did say it was
Ubuntu).
You may also need to poke a hole in your iptables ruleset.
