Do the DKIM exim experts subscribe to the mailop list ?
There is an ongoing discussion on the mailop@???
about a snafu with DKIM which implicates exim and google.
The original report of the snafu (google rejections caused the list to
auto-unsubscribe over a hundred subscribers of the list):
https://chilli.nosignal.org/cgi-bin/mailman/private/mailop/2019-April/013974.html
A description of the sending system that caused the issue:

A suggestion for the exim developers:
https://chilli.nosignal.org/cgi-bin/mailman/private/mailop/2019-April/013994.html
Basically a user with a stock debian exim setup (version number yet given)
sent a message to the list with some signed non-existent headers; when the
list passed the message on it generated these headers and google
failed on the signature discrepancy.
I believe that the list archive links above are member only,
