The point there was that exim 3 is old and very much outdated, and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

dpkg-reconfigure exim4-config

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.
