Passive Spam Block List
This interface allows you to find out whether an IP address is/was listed
in the PSBL and why. For every IP address that is/was listed, the site will
show you the time(s) a spamtrap received email from said IP address, as well
as the time(s) the IP address was removed from the list.
The host 22.214.171.124 has not been listed in PSBL in recent years. Maybe you are looking at the wrong blocklist?
