Part of my desire here would be to actually put the code for this site 
right in the 451 return code.

I've got my own issues with them, and we wouldn't be serving the same 
purpose.  My whitelist would be PURELY a dynamic list of "people not to 
greylist", not "people to give additional kudos in SpamAssassin, etc." 
DNSWL has added a bunch of mail relays (like LiveJournal) which relay mail 
for a given forwarder account but there's no logic in my spam filters to 
know to look "past" the livejournal servers for the actual spam source. 
(Short of adding livejournal's current MX ip to trusted_networks).  I 
digress.

Greylisting.org suggests something called "peer to peer whitelisting" -- 
which seems odd to me because, well, why should I install support for 
another protocol if it's inbuilt to (and possible with) the DNSBL 
protocol, on a nearly universal level?
