What's the point of wearing an atps record if it's not called out in a DKIM signature?  (I wouldn't have tested it anyway).

What's the point of ARC-sealing a message which is not arrived from an external ADMD?


I'm rather happy with the amount of gibberish I currently get.  For this Benny's message it was:
