That's a good point. The DNS lookups are expensive. (And on a random
test of the DNS lookups I figured they took more time than they were
worth. It takes hours to days for new spam sources to percolate into
the DNS lookups. By then you've received a dozen spams that passed a
DNS test giving them an artificially low score before the rest of SA
kicks in. If I am going to have a low escaped spam count SA needs to
be well trained. At that point it is already catching the spam a DNS 
check would maybe tag. So I turned DNS checks off.

(I also have auto-white-list and auto Bayes learn turned off.)
