Exchange 2010 users bombard by backscatter notification emails

Recently our Exchange users received a lot Delivery notification emails from Exchange Administrator, I know this is "backscatter" type email, end users just get bombarded by this kind email, how can I stop the administrator from sending out these kind emails? I've did research but all technotes that I found was talking about how to disable Exchange from sending NDR to other servers.
Thanks in advance!

The email looks like this:

Some anti-spam devices/services can help deal with backscatter. Some devices (such as Barracuda) can tag outbound email, thus any legitimate NDR coming back would have a tag. So no tag, it gets thrown out as junk.

Since your question has been marked as neglected, I have also added some more topics to help bring it to more Expert's attention.

Exchange 2010 default defense is very limited.

you will need a 3rd party AV/Spam service as they will treat backscatter and scan whether it is legit email or not.

further, Exchange 2010 is soon will be out of support so i will recommend you use something other than Exchange.
