That is my interpretation also. The ability of many MTAs to work with implicit domains internally is outside 5322's scope.

We are not discussing here the fact you can put 2 mailboxes in a From: but
that the display part must be between double quotes.


that's the point.

The message in question look like an auto-response from Yahoo!.
I *assume* it should only have one sender but due to $something there where quotes missing.
I'll forward the message headers to Yahoo! off-list.

Anyway, as this message was valid per RFC 5322 but invalid per RFC 7489
OpenDMARC correctly rejected that message. No bug so far.
