Does this line mean that the authentication has already failed? Or is
it the message that the authentication has started at this moment?
Does anybody know how I can get a more informative log? We have
already set smtpmail-debug-info and smtpmail-debug-verb to true.

Good to know. Then setting up another MTA for the system won't solve
the problem. I was in doubt anyway, since exim's mainlog doesn't
mention anything when I send a message with Gnus.
