MAILBOX FULL / ATTACHMENT TOO LARGE NDR MESSAGES NOT SHOWING UP FOR EXTERNAL ENTITIES
Greetings.. My current problem is that when a user from an external domain (Gmail / Earthlink etc.) sends a message to one of our users, if the user doesn't exist, they will get back the standard 550 error and their original message. However, if the mailbox is full, or if the message attachment is too large, all the user receives back is the following:
From: postmaster@nyee.edu
To: user@somedomain.com
This is an automatically generated Delivery Status Notification.
Delivery to the following recipients failed.
user@nyee.edu
--------------------------
There is no reason / error code, or original message included in this response. For internal users however, it shows up with the 'Mailbox Full' message as expected.
We are running Exchange 2003 SP2. Also please note that we have the 'Allow Non Delivery Reports' option checked off in Exchange System Manager.
From: postmaster@nyee.edu
To: user@somedomain.com

that thread is pretty much a philosopical and best practices discussion of whether to enable NDR's or not..
we want them enabled, and they are in fact going out.. we just want the actual error code and the original message to be included. Our Barracuda Spam Firewall filters out unknown recipients for us.
We basically have malformed NDR messages. And we checked with Barracuda. They do not strip anything out of the NDR's.. It is quite odd..
The message below is an NDR that says nothing other than that it wasn't delivered.. no 5.x.x code and no original message.. We just want to know why..
