That makes debugging next to impossible.

What does exim -bt dgonzalez@??? print?

... which is usually prevented by exim refusing to send to itself.

I suspect that exim is sending to your _official_ IP adress and gets
its own connection NATted back to itself by your router.

If this is the case, you need to tell your exim to deliver internal
messages to the exchange box which is information not available from
the public DNS: Take a look at the hubbed_hosts router which is there
for this reason in the Debian setup.

Looks clumsy. Why isn't your DNS able to give that information to your
Linux host?
