Inside your Network. You'll need to see where the mail is originating from to shut down the problem machine/s and repair them as required.

Can you look at the mail that is being qued

And find out where it's originating from.

Depending on what's happening you may not be able to do this as it may disguise the sender and you'll have to go digging though with a 1K node LAN you should be able to narrow down which part of the LAN has higher than normal traffic on it. It will be a bit slower that way but at least you should be able to work back to one of the smaller subsections to find the machine causing the problem.

I know that it's painful but then again if the End Users did as they where told to do we wouldn't get to have any fun would we?
