To restrict database lookups to a subset of domains use the "domain = "
table property. IIRC you may be able to negate the condition to exclude
all but a given set of domains, or do that with 'if !/pattern/' in regex
tables.
domain = !hash:/some/table
domain = !inline:{ {example.org = skip}, ... }
domain = pcre:{
{ if !/^example\.org$/ },
{ /^/ use },
{ endif }
}
