Googlemail has been doing DMARC for a long time. It sees all messages that fail DMARC as spam, you just need to set up filters that state that the messages aren't spam ... can't you do the same for yahoomail?
as it happens, DMARC is only checked for the sites, of the original senders, that have TXT/SPF records in DNS, so a large amount of the mailing list stuff gets through happily. Of course you could just convince the owner of the DNS records to have a "~all" at the end of their SPF/TXT record which means that it allows other sites to send email, just don't consider them trusted. one domain that I used to be in charge of (guess who has blackberry users :( ): nslookup -type=TXT salltd.co.uk 208.67.222.222 Server: 208.67.222.222 Address: 208.67.222.222#53 Non-authoritative answer: salltd.co.uk text = "v=spf1 ip4:80.176.180.40/29 ip4:83.105.6.168/29 ip4: 81.142.120.16/29 include:srs.bis.eu.blackberry.com ~all" On 22 April 2014 20:27, Reginald Beardsley <[email protected]>wrote: > I'm glad to see that there is at least a temporary fix for the Illumos > lists.
