Exchange 2003 Generic NDR report

Last Modified: 2012-05-06
I have a user that received a  generic NDR from my local Exchnage 2003 server yesterday and I received the same message today as I was testing. I am confused as to why I receive a generic message instead of the full NDR. The generic message follows:

This is an automatically generated Delivery Status Notification.

Delivery to the following recipients failed.

I removed my email address from the message above, but it was on the NDR.

Now I know that the message is due to an attachment being larger than 10 MB, but why don't I receive the full 5.2.3 NDR?  While testing today I sent the email from both an OE 6.0 & from a Gmail account & both of the accounts received the generic message. When I tested on the local domain (my account to a co-workers) I received the full 5.2.3 NDR. Another odd thing is that I took the NDR that was received in the OE 6.0 account & forwarded it as an attachment back to my corporate account (Running Outlook 2007). When opened the attached email in Outlook 2007 it was not the generic NDR but the full 5.2.3 NDR. Is this due to a setting on my exchange server or limitations in OE 6.0 and/or the gmail account?   How can I get the full NDR reports to be sent?

NDRs are only generated with the full text if the server gets something back to report. Otherwise the message just comes back.
If you are not seeing a reason code then that can be caused by interference in the SMTP Traffic - firewall scanning port 25 for example.

Exchange (as with all SMTP servers) is very much dependant on what it gets back from the remote site.
