What is the Spamhaus Blocklist (SBL)?
The Spamhaus Block List (SBL) is a realtime database of IP addresses of spam sources, including known spammers, spam gangs, spam operations and spam support services. SBL listings are made according to policies outlined in SBL Policy & Listing Criteria.
The database is maintained every day, around the clock, by Spamhaus Project team members around the world.
