Look a few lines above this. Why did you accept mail for a non-existent

But I do *not* accept mail for non-existent users:

You don't appar to be an open relay. It's more likely that a machine on
your network is infected.
Can you post log entries for a message that originates on your network,
but is not legitimate email?
If not, it's more likely that someone is using you as a forged sender
address/IP. in this case, can you get the headers from a supposed spam?
