In other words, if SA looked up abc.spammer.com.sc.surbl.org and the abc part was actually a wildcard, would the local caching nameserver cache abc.spammer.com.sc.surbl.org or *.spammer.com.sc.surbl.org ?
abc.spammer.com.sc.surbl.org
The local DNS server never sees the wildcard.
Ok, definately no good from a point of view of local caching then, which is what I thought. The current method of stripping the domain back to the registrar level and querying that seems to be the most efficient from the client end perspective, as randomized subdomains can be efficiently handled since only the base domain needs to be cached...
