Hello Juri,

   I'm really interested on this improvement.

I could suggest a lookup table based on DNSBL, like Postfix does.
In this case it should be a "DNSWL".
In Postfix/postscreen I already have public and private whitelists of 
IPs DNS based.
If DMARC could use this data it could be integrated easier with current 
solutions.

Thank you very much
Best Regards
Marco
