It doesn't appear to be published in DNS currently. You can check by using nslookup to find a TXT record for the name _dmarc.att.net for att.net. Yahoo's is at _dmarc.yahoo.com. Anyone using the sbcglobal.net domain will be using Yahoo's mail system. I noticed that Google has a DMARC record published for gmail.com, but it's set to "none." Google.com is set for "quarantine." -----Original Message----- From: LISTSERV List Owners' Forum [mailto:[log in to unmask]] On Behalf Of Jeff Kell Sent: Tuesday, April 22, 2014 6:28 PM To: [log in to unmask] Subject: Re: Problem now with From: *@aol.com Would ATT.NET be affected by any of this DMARC madness?
