Someone is sending a ton of spam out from my server but I can't figure out who the sender is. I attached a few lines from my log. The sender appears to be 1Ounp6-0008So-0z, is that some sort of ID created by exim?

Thank you

Hi itsofmi,

You probably have SMTP relay enabled.  Some spammer is just routing his mail through you to mask his true identity.

Not sure (I'm a Sendmail guy), but this command should show you queued messages with the sender and recipient addresses:

# exim -bp

So if you still have spam queued up, you can see the sender address

You should be able to look at the network packets and examine in incoming IP addresses.  If you're acting as an SMTP relay there should be a lot of connections from a single address.

Try:

# netstat -an |grep :25

That'll show you active connections on port 25.
