Hello Lookinglass.
And welcome to WTT Forums.
I can understand that your present problem can be quite frustrating.
I will look into the situation and post back to you shortly.

You can add me to the list of not getting email notifications. I just checked and there should have 2 today. None showed up. It seemed to be working prior to today.
It's a hotmail account.
I am fine, back with my private email account for notifications, all coming through as expected.
I did change to an account with www.care2.com for a few days, (when we last had a problem) that worked well, but changed back yesterday and all still works fine.
Email services are understandably protective of their spam detection algorithms. However, using data provided by their Smart Network Data Services and some conjecture based on experience it seems only a few people marking email as spam can cause the email for all hotmail users to be delivered to the spam box (or even blackholed). It seems this threshold is reset everyday, and gets higher over time.
So let use this as an example. Someone accidentally subscribes to the malware removal forum and doesn't know how to unsubscribe. They get sick of them and start marking them all as spam. Maybe a couple of other people hit the spam button by accident. Next thing we know all WTT email is being delivered to the spambox. The next day it resets, and email is delivered normally again. When first changing IP addresses, it seems this happens much more frequently, so a trust must be built over time, where it takes a larger target to trigger the spam designation.
While it's inconvenient, it's need is driven by ever resourceful spammers, and it will improve over time. Hope this helps.
