Could you post the log please? It might help a little bit.

You can find the Postfix faq here:

It may give you the answer you're looking for. Also, you might want
to track down the ISP for the IP that you believe is using your
box as a relay. This is illegal, and I believe in many states you
can prosecute the spammer, which I heartily encourage you to do.
They are abusing your network and resources, as well as inflicting
unwanted intrusions on a large number of other folks - if you lack
the resources/expertise to track them down, please post the IP to
the list rather than protecting them and allow someone from the list
to do it.
Take care,
