Comment (by simonyump):

 Is this a Google-specific thing regarding the `Sender` header?  Or for any
 receiving MTAs that are using DKIM + DMARC?

 And is it relevant only when the sending MTA applies DKIM to the message?
 What if DKIM is not used by the sender?

 If anyone could supply links to official methods of handling this issue,
 that would be useful.
