[wplug] figuring out where mail sent from your box came from

[Russ Schneider]

Seems like someone was spamming AOL from one of my boxes.

How can I tell from the logs whether this was a user on my box sending 
mail from the box, or someone relaying mail from an outside server?

I'm assuming if someone is sending it from an outside server, I can simply 
block port 25 and be done with it?

I'm running postfix on Mandrake, BTW.
