That would be because I was replying to a message that came through
before I fixed it. This one should be fine (I hope!)

That is almost exactly that was happening. All inbound mail is scanned
by 'edge' boxes, then handed off to a delivery server (out-b) and then
to the mail box server. The Message-id header was being stripped at
the edge, then replaced by out-b, which caused the invalid message-id
problem (Which I then replied to etc, etc).
I think we are there now (Fingers crossed!).
