ABOUT THIS TOOL
How the blacklist check works
The Blacklist Check resolves a domain’s mail exchangers and performs selected DNSBL lookups for their public IP addresses. DNSBL results are provider-specific and can change quickly, so a listing should be verified with the relevant blacklist operator before taking remediation action.
