Run the full 'check' audit on up to 25 domains in one call (each with score + grade).

Parameters

Comma-separated list (or array) of up to 25 domains to run a full health check on in one call.

If true, skip the DNSBL reputation lookups in 'check' (faster; blacklist is the slowest section — many IP×zone DoH queries).
