Email bounce (due to bad 'from' param) from yahoo on new wordpress + ubuntu 14.04 one click server image

Posted on March 10, 2015

Yahoo is bouncing emails from my new wordpress install. I am using Contact Form 7. Gmail does not bounce the exact same emails. Postfix log included below. Obviously yahoo does not like my FQDN “from” address… anyone seen this before? Anyone got a clean workaround for this?
