Very strange NDR!!!!! Sender and receiver are the same.
If anybody has solution please reply.

Hi Mihir
Thanks for your reply
I am sure there is no duplicate email.the NDR is generating automatically.

Hi,
It seems a virus generating mails. Please scan these client machines.. Also check with your database if you could found any looping there..
Regards
Mihir
I already have scanned twice and every day I found one tracking cookies with status deleted.so yesterday I deleted the internet cookies from client machine.
let me monitor two days.
and please tell me how to check database looping.
Thanks & Regards
It is tool need to run against the tracking logs to find out the looping. It will say you about the msg header... I am not sure where you can get it.
could you please tell me the name of that tool?
loopdetect.exe
msgtrack-loopde
Thanks Mihir
I tried to google but couldn't find this tool.
users are still receiving NDR.
If the sender, recipient or subject are the same, I would create a transport rule to drop messages that meet that requirement. If these users are not sending these emails the messages are most likely the result of virus activitiy.
You will want to make sure all of the clients and servers in your environment have been scanned for viruses, however it doesn't have to be someone inside your organization that is sending these virus emails, it just needs to be someone that has the e-mail addresses of these people.
