I've gone and confused you, I think. My comment was intended as a remark
about the necessary work involved to check that some things weren't
broken if a change was made. Using the word "received" isn't precise
enough. Please forget the above remark.

Yes. The message ID is generated immediately after the headers have been
successfully received, at the point when Exim needs to create the file
in which to store the body. That is, at the first moment when the ID is
needed. (If the message is abandoned, Exim clears the field before
returning from the receiving function.)
