Yes. Oh, and yes it is.

Not directly relevant, since once Exim's passed the mail on, it doesn't
matter what the second MTA does with it.

This is a safety precaution. You're probably almost there, if you're
getting this message, and are just missing the allow_localhost option on
the SMTP transport which you're using.

As per the Exim Specification, section 19 (The SMTP Transport),

-----------------------------< cut here >-------------------------------
allow_localhost                 Type: boolean                  Default: false


    When a host specified in "hosts" or "fallback_hosts" (see below) turns out
    to be the local host, or is listed in "hosts_treat_as_local", Exim freezes
    the message by default. However, if "allow_localhost" is set, it goes on
    to do the delivery anyway. This should be used only in special cases when
    the configuration ensures that no looping will result (for example, a
    differently configured Exim is listening on the SMTP port).
-----------------------------< cut here >-------------------------------


I suspect that this is all that you're now missing?
