While I'm intrigued by the discussion about the domain name isn't visible and thus may not be as important to protect as we originally thought, I'm less convinced by the notion that all of the RFC5322.From is disregarded by the preponderance of users when deciding what level of trust to put in the message's content. That suggests we blindly open and read absolutely everything, and I suspect that isn't the case. -MSK
