Look for has a 'whois' program. If I get some strange mail I can always
run whois on the IP and see if it's the same domain as the From: line.
Here's an example from some recent spam.

So, as you can see, it's a false IP. Further, I would have expected a
domain in the 'Received:' header like this genuine one

Received: from ship.ie (manson.emmplus.ie [62.17.172.66])
