Why is it too late? All that has happened is that Exim has received the
MAIL FROM command. It hasn't done anything with it. If you put in your
ACL
require authenticated=*
the effect will be to reject every RCPT command if there was no AUTH
before MAIL. Previously, MAIL would have been rejected. However, it is
better to reject RCPT, because there were (maybe still are) MTAs that
don't take a rejection of MAIL as serious. They keep trying.
