That is my interpretation also. The ability of many MTAs to work with implicit domains internally is outside 5322's scope. - Roland On Wed, Apr 6, 2016 at 9:41 AM, A.

Franck, 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. Thanks!
