although modern dns blacklists are rarely used as educational tools, their function as an email blocker and filter still serves as their primary purpose to this day. in fact, almost all of today's email servers support at least one dnsbl in order to reduce the amount of junk mail clients using their service receive.

the distributed sender blackhole list was a dnsbl that listed ip addresses of insecure e-mail hosts.dsbl could be used by server administrators to tag or block e-mail messages that came from insecure servers, which is often spam.. the dsbl published its lists as domain name system (dns) zones that could be queried by anyone on the internet.. dsbl is a dead rbl as of may 2008.
this results in a simple listing policy: an ip address gets added to the psbl when it sends email to a spamtrap, that email is not identified as non-spam and the ip address is not a known mail server. removal. removal of ip addresses from the list can be done by anyone.
