Passive Spam Block List
psbl.orgThe Passive Spam Block List (PSBL) is a community-driven DNS-based blacklist designed to reduce false positives in email filtering by allowing any user to instantly remove their mail server’s IP address from the list. It operates on a simple policy where IPs are listed only if they send spam to traps without being identified as legitimate, aiming to distinguish between compromised hosts and known malicious servers. This approach facilitates easier remediation for legitimate users sharing infrastructure with spammers while maintaining a barrier against bulk unsolicited email.
