Hi,
I just spotted in our mailbox that one of the DMARC reports we have sent
out have bounced back from O365. In this case there is an additional
level of forwarding by mimecast which I figure breaks everything even
though there is ARC in place. Am I missing something or is there an
additional pro
Was I really not that clear? I’ll go back and correct.
Microsoft is attempting to authenticate the visible (5322) from address. So
either the SPF domain or the DKIM domain needs to be aligned with the visible
from.

Particularly I'm wondering if the "from" address mentioned is the visible
from address or does it mean the from address in the header? Anyone know?
