Well, no. Per the headers:
Authentication-Results: mx.google.com; spf=neutral (google.com: centos-bounces@centos.org does not designate permitted sender hosts) smtp.mail=centos-bounces@centos.org; dkim=neutral (body hash did not verify) header.i=@; dmarc=fail (p=QUARANTINE dis=NONE) header.from=harte-lyne.ca
The p=quarantine setting from his server explicitly requests that the message be marked as spam if it s not sent from an authorized server, which don't include the centos list server. So it is accepted and dropped in the spam folder as requested.
And at the moment, he is the only list member that posts regularly from a server with this setting. (We don't even see ones with p=reject, they'll bounce and get kicked off the list).
I guess that last part isn't true. Apparently forwarded yahoo senders also go to spam instead of bouncing:
Authentication-Results: mx.google.com; spf=neutral (google.com: centos-bounces@centos.org does not designate permitted sender hosts) smtp.mail=centos-bounces@centos.org; dkim=neutral (body hash did not verify) header.i=@; dmarc=fail (p=REJECT dis=NONE) header.from=yahoo.com
Anyway, you can see a domain's dmarc setting with: nslookup -type=txt _dmarc.domain.com and see the p= meanings at http://www.dmarc.org/faq.html In particular, see http://www.dmarc.org/faq.html#r_2 for the effect on mail lists. "If the domain in the From: header is from an organization that publishes a DMARC record, the email is likely to not be delivered."
