Exim has a debug mode.
...
You will see the processing that exim does, and should be able to
infer at what point it diverges from your needs.
Thanks. I should have tried debug before asking.
Debug alerted me me to add lines in /etc/email-addresses.
Appears this debug run is incomplete but I don't recognize a clue.

"FIXED_NEVER_USERS can be set to a colon-separated list of users that
are never to be used for any deliveries. This is like the never_users
runtime option, but it cannot be overridden; the runtime option adds
additional users to the list. The default setting is “root”; this
prevents a non-root user who is permitted to modify the runtime file
from using Exim as a way to get root."
Meaning that root is not allowed to send email? If so, the "problem"
is simply me attempting something prohibited; but prohibiting the
administrator from sending email seems unrealistic. What is the
reality?
Thx, ... P.
