In my experience, based on three posts on Sat, 5 Apr, From: a yahoo.com address to a list which has about 240 individual message deliveries per post, about 90 of those to about 8 domains bounced. gmail.com was not one of the domains that bounced the posts. Gmail may have changed it's behavior in the last 8 days, but this reason doesn't look like the ones I've seen. E.g.: aol.com/netscape.net/compuserve.com: 521 5.2.1 : (DMARC) This message failed DMARC Evaluation and is being refused due to provided DMARC Policy yahoo.com/sbcglobal.net: 554 5.7.9 Message not accepted for policy reasons. See http://postmaster.yahoo.com/errors/postmaster-28.html comcast.net: 550 5.2.0 mfuB1n01M0MH6DU0XfuCv5 Message rejected due to DMARC. Please see http://postmaster.comcast.net/smtp-error-codes.php#DM000001 hotmail.com/msn.com: 550 5.7.0 (BAY0-MC3-F56) Unfortunately, messages from (72.52.113.16) on behalf of (yahoo.com) could not be delivered due to domain owner policy restrictions. Bottom line: I don't think this is a DMARC bounce. -- Mark Sapiro <m...@msapiro.net> The highway is for gamblers, San Francisco Bay Area, California better use your sense - B.
