Looking at your headers.... You are on a cable model, with dynamic IP. You have not properly configured your mail system. It is sending directly, but you don't have a proper domain name. Many systems are configured to reject mail that does not come from a proper server. Another issue with yours is that the names don't match. The name you give and your IP number do not relate to each other. Stuart's ISP is overly aggressive about this. It rejects even properly configured mail hosts if the IP number in certain subnets. It rejects mine too, unless I let Comcast sensor it first. You will have this problem with several of the mainstream providers, including AOL and Juno. The reason they do this is spam and viruses. Most spam and viruses come from compromised computers on dynamic IP's. The headers look just like yours. My system rejects all mail from hotmail, because they can't configure their system correctly, and the names don't match. The idiots have their relays configured so all of their mail looks like it came from a spambot. The standard recommendation is that you send all mail through your provider's relay. In your case, this is what you should do. What I have (with a real domain name) is to send most mail directly, but go through the relay to certain destinations.
