Ok, more mail has come in and with "auth_debug = yes" set in the
dovecot.conf file, the following was logged as I moved through the
mailbox. Each place where you see a "new auth connection" entry was
where I had selected an unread message, it didn't display, and I clicked
on another message to get off the one that wasn't displaying. Clicking
back on the previously unread message displayed the message just fine.
I replaced my login ID in the log with "xxxxxx", just to be clear. :-)
