How do I use the Spamhaus Hash Blocklist (HBL)?
The Hash Blocklist (HBL) contains cryptographic hashes associated with malicious content, as opposed to IP addresses or domains. Query a hash against the list to determine whether the content element has a bad reputation.
Documentation and more in-depth technical details can be found on the Spamhaus Technology Ltd website.
