This is from the spec file, pay attention to the last sentence:
hosts_require_auth Use: smtp Type: host list† Default: unset
This option provides a list of servers for which authentication must
succeed before Exim will try to transfer a message. If authentication
fails for servers which are not in this list, Exim tries to send
unauthenticated. If authentication fails for one of these servers,
delivery is deferred. This temporary error is detectable in the retry
rules, so it can be turned into a hard failure if required.
I personally don't use anything more than the most basic retry rules,
so I do not know how to specifically do that last bit, likely others
will be able to provide better feedback.
