My guess is that you will not see the IP address of the sender when you 
receive a message through Facebook.  Facebook doesn't present full message 
headers on messages that are sent through the website.  Since all 
communication happens through the website, that provides a layer of 
abstraction if Facebook/Myspace/insert_portal_here chooses not to reveal 
the sender's IP address to 
you.
