Correct. You would enter in SMTP commands and see what would happen to
the message. Exim applies all the same rules that it would for a normal
SMTP session. Here's your script:

        EHLO issola.localdomain
        MAIL FROM:<root at issola.localdomain>
        RCPT TO:<ccurley at dzur.localdomain>

At that point it's going to puke on you and a few lines up you should
have your explanation as to why.
