They're not meant to block spam. They're meant to authenticate where
the email came from.
Basically, DK and SPF make whitelisting domains feasible. If you know
that AOL actively keeps their users from spamming, and AOL publishes
SPF/DK records, then you can whitelist all email from AOL. Assuming it
passes the SPF/DK test, that is.
