I'm seeing transactions like the following being logged in maillog:

Any idea why that is?  Does it represent a failure?  Or is the message being
redelivered without authentication?

And why is authentication required on the loopback address?

Make sure your /etc/mail/access contains at least

# by default we allow relaying from localhost...
localhost.localdomain           RELAY
localhost                       RELAY
127.0.0.1                       RELAY

It does, so that's not the problem...
