They want their organization to be seen as secure, so they don't want to be on the Buzzfeed list of Fortune 500 companies that have neglected to secure their domains with DMARC. Well, that's the problem, isn't it? If your expectations for e-mail are shaped by experience with paper mail and you don't realize how different an organization's internal highly controlled mail system is from e-mail on the outside, you're inevitably going to be surprised, sometimes unpleasantly. I would like for us to avoid the Yes Minister Tautology: We must do something, this is something, therefore we must do this.
