Until spammers figure out they can send mail From: spam...@evildomain.com X-Original-From: whate...@yahoo.com DMARC doesn't stop it because evildomain.com doesn't publish a DMARC policy, and the 'evolved' MUAs display the message as if it's from whate...@yahoo.com, just what DMARC is intended to stop. -- Mark Sapiro <m...@msapiro.net> The highway is for gamblers, San Francisco Bay Area, California better use your sense - B.
