The most widely used blocklists (ZEN = SBL, XBL, PBL, CSS). Not queried here: Spamhaus refuses queries from shared public resolvers.

Getting delisted: Check an address at check.spamhaus.org. XBL and CSS entries can usually be removed there once the cause is fixed; PBL lists dynamic ranges by design.

Always find the cause first: a compromised account, an infected server or a customer's VM sending spam. An address that keeps sending is listed again within hours.
