Maybe not for a court of law. But when I see a forwarded message with our address in the cc list and obtained directly from another party on the same cc list then, on the balance of probabilities, I will accept that as sufficient evidence. Thanks for the explanation. As there were no other email problems reported I inferred that what ever the issue was it must be external and specific to that domain. A temporary DNS outage occurred to me but the small gap in time between failure and success in delivery caused me to wonder if there was something else in play. We were also dealing with an OpenDKIM update issue yesterday and any coincidental local changes are always a prime suspect when a problem is reported.
