I got a little worried when I was first testing it as I wasn't thinking.

It was then I realised that I was still on the local box. It doesn't 
even listen on the LAN (Even though I set it up to when I originally 
configured it through deb conf) so I guess its ok although at a later 
date I will have to change the settings.
If this is giving the same heading as when it sends mail I can see a 
problem that is going to possibly occur. Some people have exim set up 
(from what I learnt reading the conf files) to reject servers that 
identify them selves with a non standard hostname, i.e. one that isn't a 
full qualified host name with domain. Linmedia is not going to pass so I 
may get rejecected because of that. Even after changing it in 
/etc/mailname and running update-exim4.conf.
Well I guess I have a lot of configuring to do.
