 That host is either the spammer's MUA, an open-relay, or an open-proxy.

The only IP address information you can trust is that which is put on the message by your own MTA, and even that might be suspect (if there is a security hole in the MTA which could effect the recording of this information).

 All of which are complicit in the sending of spam, so you do have
 information you can use to prevent further spam from being delivered to
 you in the same way.

Maybe. If that machine also sends you a lot of legitimate e-mail, are you willing to cut your nose off to spite your face, based solely on the IP address information?
