Gmail has a new interface for displaying the raw version of a message. If you click the arrow icon next to “reply” and then “show original”, you’ll see a list of headers like “message ID”, “from”, “to”, “subject”, “SPF”, “DKIM”, a link for downloading the message and then the actual text of the message. Until now, Gmail only displayed the text of the message.
The new interface also displays help center links with additional information about SPF records, DKIM signatures and the DMARC standard. All of these values are useful for identifying spoofed email messages, which forge the sender address.
