Hello Danny,
Yes sir that is my mail server. Thank you very much for doing the test. I am not sure how the relaying was being done? I guess everything is ok now? Here is a sample of the smtp file I was looking at I am not including the actual ip address But as far as I can tell looks like this person was trying to relay through me? I have about 50 of these with the same ip address doing the relaying. I did a ip block here so I know who knowns the ip. Wonder if I should send the smtp log to the ip owner or just drop it?
