Microsoft Hotmail / Outlook.com's SNDS (Sender Network Data Services) portal is a useful interface where you register to be able to look up reputation data specific to your sending IP addresses. In my "How to troubleshoot Microsoft Outlook.com / Hotmail Delivery Issues" article, I suggest signing up for it.
People sign up for it, then they invariably ask, OK, what do I do with this thing? What am I looking at? What do each of the fields mean?
It turns out that Microsoft has you covered! Check out the "Data Provided" section here. They break down filter results, explain what they mean with regard to time frames, trap hits, and so forth.
It's not the complete guide with regard to "what do you do next" but it's a step in the right direction. I've found it quite useful and I hope that you do, too.
