Spoofing and SPF

hi, I am trying to find information on preventing people
spoofing email sent to a domain.

For example my server handles email for the domain
example.com, and the only people who
can send from this domain are either internel or on a couple
of external ip addresses.

How do I stop everyone else pretending to send mail form
a.userexample.com to 
an.otheruserexample.com?

I can't seem to find much useful info so am probably
looking in the wrong places.

Kind regards

Benedict White
