whitelist for policyd ?

[joximu]

policyd-weight is not the same as postgrey.

policyd-weight: is like several Blacklists and some other spam-recognition tools combined together and weighted...
So: you'll need a whitelist for the poor guy sending from a spamming IP address.

postgrey: it forces the mailserver to send the first mail to a certain person twice, so the old spam senders were sorted out.
You'll need a white list there for the mail servers which do not comply to the rfc standards (there once were some windows smtp machines which did not send a mail twice...)
