            Your anecdotal observations are flawed. Postfix makes new
            connections to the MX hosts in the order supplied by DNS. Claims
            to the contrary need to be backed up with detailed logging for the
            transactions in question, including not only the final delivery
            success/fail indication, but also any prior connection attempts
            or partial deliveries.

            Your assessment of the probability is likely in error. Typically,
            the debug logs are not needed. Just include all logging from
            "postfix/smtp" (not postfix/smtpd) for a few minutes before and
            after a "failure" to use the best MX hosts.

    Only status=sent/bounces and final failure for status=deferred (after
    exhausting all MX hosts) are logged with the queue-id. Connection attempts
    are logged without the queue id, but carry the same process-id as the
    final final bearer of bad news. The messages in question are those for
    the same pid, that immediately precede the queue-id in question and lack
    a queue-id.
