this mail was rejected by one of the (newish) inbound relays for
postgresql.org, the problem with diagnosing this in detail is that the
message is very old. We don't actually have logs going back 10
generations and you sent in the complaint like a day too late :(
However if the forwarded bounce is unedited it looks extremely strange
with all the interleaved header(and mime declaration)-stuff on the CC
and the second Cc line (note the difference casing).
I would strongly suspect something tinkered with those headers but we
don't have enough data to diagnose this fully though :(
