Interesting article, I'm not sure if it applies to my situation or not. I use ImprovMX to forward several domains to one of my other domains. I think one thing the article doesn't really mention is that the domain sending the email is only one (potentially small) factor in classifying email as spam or not. Gmail has done just fine classifying different emails as spam that are being forwarded from the same domain. After all think of how much spam is sent from the gmail.com domain.
