No. Hal's report only said that most of the unsubscribed user's were hotmail. It said nothing about the From: domain of the posts that were bounced.
In fact, the fact that almost all the unsubscribed users were hotmail makes it seem that this is not DMARC, but more likely hotmail (Microsoft) blocking the sending IP.
Can anyone check that Hotmail has published a "p=reject" DMARC policy?
