It's perhaps worth pointing out that in 'local' mode - that is, where an
application is generating a mail and calling a command-line binary to
push it into the Exim queue - there is no way to prevent the messages
getting into the queue without causing unintended consequences on behalf
of the application concerned.
That's why the non-SMTP ACL has no knowledge of domains etc, and all the
work has to be done once the message is queued - hence Lena's excellent
and simple explanation above.
