I know any RBL lookups will remain in BIND's cache and I would hope that the same happens in regards to Razor and the like. I also thought that there might be expiry settings for info that could be tuned.
Anyone have any suggestions?
Only peripherally related to SA, but I figure someone here is bound to
know the answer: do any of Razor, Pyzor, DCC or any of the other peer
spam rating systems cache queries? That being, if we get the same spam
sent to a thousand staff as individual mails, how many lookups do I get,
3 (one for each protocol/client) or 3000?
