Forget including "Ubuntu" in any searches, there is nothing of note that
is distribution specific about configuring these services.  Stop
thinking in a distribution-centric mindset.   It is Postfix, Cyrus,
etc... *NOT* Ubuntu, CentOS, openSUSE....

You'll need working DNS in your private network before anything else
will work.  Once that is working setting up everything else shouldn't be
anything out-of-the-ordinary.  Just make MX records to yourself for you
test domains [example.com/org/net is allocated for this purpose].

One handy trick is to sequester e-mail via Postfix rewriting.
