As I undestand, a smarthost is another reachable SMTP that handles to send the e-mails to its destiny, but inside my local network (what is reachable without a proxy) there is no other smtp reachable without this proxy

The point there was that exim 3 is old and very much outdated, and
you really should be using exim 4 instead.
Now, for your actual problem you need to look into what's called a
smarthost. I don't know about ubuntu, but debian (which ubuntu is
based on) will let you configure these by calling
and entering the appropriate options.
A smart host is basically like a proxy: your exim simply sends all
the e-mail it needs to send to the smarthost, and the smarthost takes
care of sending it to its destination.
