Howto config postgrey not to allow SPAM based on dnswl.org whitelist?

Howdy, 9 to 10 months in using SPAM free MIAB and starting yesterday I’m getting flooded w/ SPAM allowed thru via postgrey (and spamassassin). Log follows:

box postgrey[3624]: action=pass, reason=client whitelisted by dnswl.org (2/rare spam), client_name=sm1.vitacost.com, client_address=184.106.10.149, sender=bounce@bounces.vitacost.com,│ Fe│ recipient=david@davidwbrown.name

I tried directly entering the SPAM email address into the Spamassassin local.cf blacklist but no change.

dnswl.org has forms and such to send the email in question headers and body but at this point I don’t trust dnswl.org either.

Is there anything short of running my own dns blacklist on the MIAB server side to bounce this SPAM?

Please advise.
