Since you whitelisted all mail from the domain in question it got a
negative score of -100
If you remove that score it jumps to over 23 points, which would have
marked it as spam
The fact that borland's A record may point to another IP is irrelevant.
You have no way of knowing which IPs are permitted to send mail from
borland.com as they haven't published an SPF record.
