Somehow, out of the blue, my postfix setup is allowing relaying. I pass
all the relay tests, but a hacker has figured out how to send email
through my server without authenticating. I have checked my server for
being an open relay and all the tests are passing. The only error log
entry that is showing up that may be related is:

I updated postfix and related software, the issue is still happening. Do
these messages mean anything about my specific problem?

The log entries you show are irrelevant to your stated problem.
You need to examine logs of messages that you think should not
have been accepted or relayed.
