I want to make certain that what we're building with policies doesn't prevent eCard senders or News agencies from doing what they currently do. They should be able to 1) send a message to someone on my behalf while 2) marking themselves as the sender and 3) being able to sign the message. According to 2822, this minimally requires support for RFC2822.Sender as well as RFC2822.From. For example, consider these scenarios: From: [EMAIL PROTECTED] Sender: [EMAIL PROTECTED] DKIM-Signature: ... d=hallmark.com; ... Subject: Happy birthday from Tony or From: [EMAIL PROTECTED] Sender: [EMAIL PROTECTED] DKIM-Signature: ... d=newyorktimes.com; ... Subject: some news story These need to be validated against the sender. Yes, there are a variety of issues. And to properly deal with this issue, we also need to deal with Sender/d= above being "@bigbadguy.com". DKIM is not sufficient in and of itself, as we all know. But we need to be able to support these scenarios somehow. If we don't let this be done using Sender:, then we need to have some other way of doing it. My choice is to support the 2822 way of doing it, which says we need to support Sender:.
