Copying intended recipient on oversize message NDR

     I'd like to copy the intended recipient on NDRs generated for all oversized mails ONLY. The problem is that the sender is not configured to accept NDRs, so when the oversized mail doesn't reach the intended recipient, neither party knows the mail was not  delivered.

 I know you can modify the postmaster address as a rough and ready workaround, but then you're getting all types of NDRs sent to the address designated  'postmaster'.

I don't believe that it's possible to  CC or BCC the intended recipient on an NDR generated by an oversize mail (ref: but I do need to be 100% one way or the other.

If you need more information, just let me know. Thanks for your time.

If your server is configured correctly, then the sender should get an NDR no matter what settings they are using. That is because Exchange should reject the email for being over sized at the point of delivery. NDR blocking shouldn't take place at that point because the NDR is generated by their server.

However it is NOT possible to have an NDR sent to the recipient.

Hi Simon,
              thanks for getting back so quickly. Most senders do get NDRs from us, but this guy doesn't. Our config is solid.

Ok great. Do you have any documentation to support your answer. I'm not being pedantic. I just know that my client will require proof if possible.

thanks again

Nope - Microsoft don't produce documentation that states you cannot do something.
If you cannot find anything that says you can (and that will be the case) then that is the best you can do.
