I was looking at message tracking log in our exchagne server 2003, some spam emails look like being sent from our email server(screen capture attached).
I restricted email relay in our server (screen capture attached) and tested using open relay test (http://www.checkor.com/), it blocks it properly. Where can I check how the spams being sent from in our email server? hhhhhhhhhh.jpg ggggggg.jpg
