Should I use the Policy Block List (PBL) to block access to my webserver?
The Policy Block List (PBL) should not be used to block access to webservers, web-forums, journals, blogs, or anything else of this type.
- A PBL listing is NOT a result of any actions undertaken by the end users.
- The Spamhaus PBL is a list of IP space that should not be sending email direct to MX.
- Often these are IP ranges assigned by ISPs to broadband or dial-up customers, but the PBL does include other types of IP space.
- Any IP space that should not be sending email directly to the Internet should be listed in PBL.
- The majority of legitimate connections to webservers come from IPs listed in PBL, and should NOT be blocked because of their inclusion in the PBL.
