However, I'm pretty sure we're not the only folks in similar situations (consider, from an older thread, netscape.com / aol.com addresses). Something as "simple" as: $ dig +short _dmarc.netscape.com TXT "v=DMARC1\; p=reject\; pct=100\; ad=aol.com\; rua=mailto:[email protected]\; ruf=mailto:[email protected]\;"; (where a] this is a mockup and b] 'ad' represents an Aligned Domain flag) would allow a MAIL FROM @aol.com with a From: @netscape.com to pass DMARC. -- D -- David Romerstein | LivingSocial | Lead Delivery Engineer | www.livingsocial.com
