Unable to send messages, relay denied. IMAP does work ok.

Hello Apache James mail list.  Yes, I know from Google searches that
getting a "relay denied" error message is a rather common experience but so
far I don't have nor found a solution to this error message; when I try to
send from any one of several accounts that my James server has been set up
to handle.

I have an older version of James version 3.4.0 which I plan to upgrade
soon. I first want to upgrade my OS (OpenSuSE 15.3) and then I need to
figure out what to do about the fact AFAIK that support for the maildir
format has been dropped, and how do I import all of my users mail into one
of the new supported mailbox providers.

That said, at the moment I tried to do some reconfiguration of my Apache
James 3.4.0 server and in the process I somehow screwed up James' ability
to send email. And I don't know what I did wrong so now I am trying to
debug it. The basic problem is that James is refusing to send emails to
anyone except local users, saying relaying is denied. Sigh.

I will start with showing the contents of my smtpserver.xml, with comments
and sensitive information removed. (thank you Emacs!) and ask if anyone can
see if I did something bad -
