If you are having email delivered to Hotmail accounts but it never gets opened and you feel confident that Microsoft is null routing (DROPPING) your email, then that might be good news.
Recently I have a number of hotmail mailers that have made the discovery that Microsoft is looking closely at Return Paths Sender Score. If the IP space has no Sender Score reputation it is almost guaranteed that the email will be null routed and never delivered to the inbox.
To solve this problem, you must build a SenderScore Reputation. Send your best, clean data to general internet domains. Keep the volume low such that you do not alarm any spam watch-dogs. The emails will be reported by the ISPs that use Return Path. This includes, Cox, RoadRunner, USA.NET, Mail-Trust, BlueTie, Earthlink, Excite, Rackspace Hosting, Tucows managed domains and Yahoo.com managed domains that include AT&T.
Today I noticed a number of IPs were being manually blocked at Microsoft. I made this discovery because I subscribe to Microsoft SNDS. You to can see these reports at Microsoft and can easily sign up at Microsoft postmaster As easily as you get blocked at Microsoft you can also get unblocked. You just need to ask. They will remove the manual blocks usually within two business days upon your request.
Now the secret to getting IP space unblocked by Microsoft is easy
With you have data from Microsoft and know how to ask the right people, the right question and within a few days, sometimes a few hours the IP space block is removed.Go to http://postmaster.msn.com/Troubleshooting.aspx and at the bottom of this page you will see a link to Support. Click on Support link
The next step will require some careful attention to details.
Answer all the questions and be honest. Microsoft support will read every answer you give and will reply with additional questions as needed within a few hours. In my case I had a large number of IPs that needed to investigate thus this took three days.
After you complete and submit this form, you should expect a reply withing 24-48 hours.

Smart Network Data Services (SNDS)
Is a revolutionary Windows Live Hotmail initiative designed to allow everyone who owns IP space to contribute to the fight against spam, malware, viruses, and other Internet evils, to protect e-mail and the Internet as a valued communications, productivity and commerce tool. Windows Live Hotmail, with over 350 million active user accounts world-wide, is in a unique position to collect and analyze e-mail activity data. By providing that data to service providers, most of whom wouldn’t otherwise have access to any such data, they are empowered to use their relationship with their customers to react and take repair actions, such as preventing spam from originating within their IP space. The overarching goal of SNDS is to make the Internet a better, safer place. Working together, Windows Live Hotmail and service providers can make their respective customers happier and more satisfied with the various services we all provide.
