As outgoing was normally somewhen incoming, I'd focus on blocking the
incoming mails.

In your RCPT acl you could do something like this:

    deny    senders = bad@???
            local_parts = test
            domain = domain.com


More flexibility you'll get using some lookup for sender and/or
recipient. But it depends on the amount of blocked senders/recipients.

If you really need to block on *outgoing* side, you may conditional
(based on the sender) route (redirect) to :blackhole: or :fail:.

    black_router:
            driver = redirect
            senders = bad@???
            data = ${lookup{$local_part@$domain}lsearch{/etc/exim/black}{:fail:}}
            allow_fail


Both is not tested, but may be it shows you the direction.
