Apparently forwarded yahoo senders also go to spam instead of bouncing: Authentication-Results: mx.google.com; spf=neutral (google.com: centos-bounces at centos.org does not designate permitted sender hosts) smtp.mail=centos-bounces at 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." -- Les Mikesell lesmikesell at gmail.com
