In this specific case,the list is a list of known domains that will pass whitelist_auth, which means you can blacklist them and when they pass auth, they magically get through. As Dave Pooser posted: > whitelist_auth *@bankofamerica.com > blacklist_from *@bankofamerica.com > > I score blacklist_from at 80 points so an address that's both blacklisted and > whitelisted will be effectively whitelisted, thanks to a net -20 score When BOA sends an email, it hits the blacklist and gets a score of +80, but if the mail passes whitelist_auth (meaning it’s really from BOA), then it gets a -100. So anyone who is not BOA ends up with a score of +80. It doesn’t matter how many random domains they create. A list really would be helpful in this case. -- 'I don't like to ask them questions.' 'Why not?' 'They might give me answers. And then what would I do?'
