How do you use YOUR DK implementation to filter spam?

[T. S. <big...@gm...>]

So I'm pretty much on board with making sure my server is sending
correctly signed emails so that a recipient server can verify that I
am not spam.

My question to the list is, how do YOU implement dk verification to
help prevent spam? Are you running any sort of procmail/sieve script
to filter out email with bad signatures?

Thanks,
