No it's not. It's hotmail blocking a Verizon static IP address. They are not on any blacklist. Nor are they on a DUHL. Verizon decided to stop letting them relay off a Verizon server all the sudden. It was authenticating to it and relaying off it. I created a SPF record but it doesn't seem to help or be related to this message. There are a lot of posts in forums about this. They seem to post a message in one of Windows Live's forums and pray for someone to look at it.
