Meaning all of your routers declined (as opposed to an ACL
rejection). That begs the question why the message was not rejected
by a verify=recipient test in the RCPT ACL.

Seems clear enough. The message was not rejected by any ACL, but
none of your routers were triggered by it. This is a Bad Thing,
unroutable messages should be rejected in the RCPT ACL. But it
should be easy to debug via exim -bhc (as previously suggested) if
you can't spot it simply by eyeballing the router you *expect* to
handle this address (dnslookup, in the sample config).

Did you run the "exim -bhc <internal-server-IP-address>" session on
the external box? Running it on the internal box won't tell you
anything.
