I don't use abusix myself. Some time ago someone pointed out to me
that keys were part of the address and thus popped up in the logs and
return codes. For the providers that are known to have keys I've
implemented a hardcoded way of stripping the key itself. Other than
that they have no special treatment in filter-dnsbl.
If you're sure these servers aren't listed it might be possible that
they return some special whitelist status. To keep filter-dnsbl simple
all answers are interpreted at listed.
