check_blacklist
Read-only query against the currently configured public DNSBL/RBL providers (roughly 60, with noisy providers explicitly disabled). Provide either domain to resolve and inspect its MX IPv4 addresses or an IPv4 ip for a direct check; at least one is required. Returns each provider's listed/clean result, severity, removal metadata, plus unavailable and disabled provider evidence so timeouts are not misreported as clean. Use for mail-server reputation triage; it is not a delisting service. No auth or destructive actions.
Input Schema
| Name | Required | Description | Default |
|---|---|---|---|
| ip | No | IPv4 address to check directly | |
| domain | No | Domain name only, e.g. example.com (no URL, path, or port) |
