1 - Which page are you referring to? Can this problem be recreated everytime?

2- Ignoring the response upon your request.

3 - The feature is in our to-do list and you will see it in a future release. It's hard to give you an ETA because tasks are implemented according to their priority.

4 - There is no way to see the IP address waiting for grey listing. On a high volume server that would be too much data to track as well as to see. The default retry interval is 5 minutes, which you can change.

5 - Thanks. We will update the page.
