William Posted May 3, 2006 Share Posted May 3, 2006 I have tested for open relay on our server this has returned secure results. I have checked all of our machines for viruses and we have none. The only way that mail could be generated from our server is that the spammer is using the Non-Delivery report functionality of our mail server sending to a fictitious address at our company and the real destination in the (from) field which is then sent an NDR from our server. I have now disabled NDRs. Is there a possibility that these emails are being generated by somewhere entirely different? I suppose your reverse DNS would show were it is actually coming from. Is there any way that I could contact somebody at your company? We are really having problems being listed as many of our recipients use your service. If anyone could provide useful information as to enable me to get off this list it would be greatly appreciated. Thank you Link to comment Share on other sites More sharing options...
