What can SNDS tell you?

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.

Ask Al: What of Senderbase?

Emanuel writes: "I need assistance with Senderbase. What ISP report to Senderbase? Is there a way to view Senderbase complaints? We add all ours IPs in the feedback loop, but not in the feedback loop of Yahoo. Is it possible that the lack of a Yahoo feedback loop is the problem?'

Emanual, I'm sad to say that it has been a very long time since I have run into client issues that I believe to relate to Cisco's Senderbase. I don't know if Yahoo complaint data is fed to them, to be honest. But I'll throw the question out here and we'll see if someone else out there has some other ideas. Feel free to share your thoughts in comments, and thank you in advance!
