As long as you have "verify = sender", there needs to be a Router which
handles the address in question (provided that your ACLs aren't
accepting the message before you hit that clause).

So what do you get from:
$ exim -bt name@ip-address
?

You want to see something like:
$ exim -bt phil@192.0.2.1
phil@192.0.2.1 is undeliverable: Unrouteable address

If you get a response which includes "router = foo", what is the
definition of foo?

If it's dnslookup, then I think you have a resolver doing something
funny, faking up A records when the query looks like an IP address.
