Go to http://www.sendmail.org/ and follow the links that describe
how to stop spammers.  There's also a lot of very useful information
in the README file that comes with the sendmail-cf package.

In essence, you want to put entries into /etc/mail/access that allow
relay for the localhost and your internal (trusted) network, then
deny relay for everything else by default.  It's almost trivial to
set this up, I can't understand why the penny hadn't dropped for you
yet.

There is definitely no need for smtp-auth for what you want to do.
(Although this is way cool once you have it working, especially for
allowing "travelling staff" to post their email via that mail server
from other places on the internet).
