I just use the one built in to my ADSL router; I don't know whether it
caches. The one it forwards to at my ISP is probably bind.

I don't actually know how to do a manual query. I don't think there is
any caching as far as SA is concerned because the timeouts are
completely consistent.

That seemed to whizz past quite quickly compared to these timeouts. And
I was only using the main spamassassin program to get the debugging; I
usually use spamc and spamd so I doubt that runs the check for every
message.
