No. Neither of them will really  block that much spam. SPF may currently
help you block more spam than DomainKeys though.

You will get better results with RBLs and greylisting than both of these

They are, although  SPF is moreso. DomainKeys was better  thought out in
my opinion, but still doesn't help block  much. I have found that I have
actually blocked  legitimate messages with  both SPF and  DomainKeys and
even caused a few legitimate messages to be blocked by SPF.

With respect to  DK I don't believe it should  do anything. With respect
to SPF, I believe SPF and mailing lists don't play well together.

Note, my email probably has a DK...  Not that it has helped in anything.
