I believe someone expounded on this a bit earlier on.

Well, one option is to use a crossover cable between the two machines in
question. Another would be to reboot into single user mode, so things
like exim won't get started. Can't remember if you get networking on by
default in single user mode, but /etc/init.d/networking start should do
the trick if it isn't.

A good first step would be to use one of the online services that test
whether you are an open relay. Try googling on open relay test, or
search the list archives, it's definitely come up before. If you are an
open relay, shut down exim and test again. If that fixes it, then you
know that you have an exim config problem, and you can go from there.
