How to examine details of an e-mail I received?
I believe I've heard that you can find things like:

 - IP Address an email was sent from
 - Machine Name an email was sent from
 - Various other bits of information that are not visible when viewing an email

If you look at the innards of an email.  Is this true or am I way off base?  If it can be done, how do I go about finding that information?

The email is from a Yahoo account.
