Of course they're still getting tagged as spam. A score of 2.0 is way, Way, WAY too low a score to be reasonable. At my site it's set to 3.5, and it's still very aggressive, requiring plenty of whitelisting. I wouldn't set it to anything lower than that. You're better off keeping it at 5.0, and raising scores (and creating new ones) to push spam higher, instead of trying to push ham lower. Also, nowhere in that header does it show USER_IN_WHITELIST_TO actually hit the message, so your whitelisting didn't apply anyway. I suspect this is because whatever MTA you're using couldn't do the reverse lookup on 143.166.148.206 (it just says "from unknown").
