Gmail providing easy-to-read Auth Results
This is pretty slick. When is the last time you selected "View Source" in Gmail to look at the raw headers and body content of an email message? As of a couple of days ago, Google has added some nice new info to this feature, showing an easy-to-understand summary of authentication results. In this example, it's highlighting that SPF, DKIM and DMARC are all working correctly.
This is all info you could find by looking through the email headers. But it's nice to see it called out in this way; it saves some digging and gives you a very clear understanding of how the Gmail platform sees the message.
