It's one of the most popular domains in the world ISPs.
Microsoft (Outlook.com and Hotmail.com) Feedback Loop are IPs based.
Smart Network Data Services (SNDS) and the Junk Mail Reporting Program (JMRP) are two services Outlook.com provides for email senders to receive feedback on their mail.
SNDS provides an overview of your IP addresses and shows relevant statistics like approximate inbox rate, complaint rate, and trap hits.
JMRP lets you set up a feedback loop, so you can receive copies of messages Outlook.com users mark as junk.
To join SNDS and JMRP, please enter your IP addresses and complete the FBL form. After authorizing your access to these IPs, you will be enrolled in both programs.
Log in with your Microsoft account. (or create one if you don't have it)
