As explain there, 88.blocklist.zap is Microsoft maintained black-list.
Because of its operating mode, this blacklist can’t be monitored from common online tools like MXToolbox.
However, there is a Microsoft live online tool to query status of your IP, and may be used to follow blacklist IP status, as other anti-spam and antivirus tools implemented on Microsoft online applications.
This monitoring tool is available with a simple live account.
You need to request access to your IP status first.
