Notify External Senders of Delivery Failure due to attachment size in SBS 2003
Posted on 2010-09-09
I have been having trouble finding the exact answer to this question. Here is the situation. The company I manage routinely receives large attachments from clients. Our default max file attachment and message size is set to 10 MB. This is something that I do not want to change however when a
message is sent to us by our clients and fails to make it to its intended recipient due to exceeding
this size limit no one is notified. The message simply fails and neither us nor the client knows that
it did not come through.
I am currently running SBS 2003 Premium with Exchange 2003. I am thinking that it has something'
to do with enabling custom NDR's for the status codes 5.2.x but I can not seem to find a guide for
doing exactly what I want which is when a message is sent from someone outside of our domain
I need both that sender and possibly the recipient to be notified that the message failed due to
attachment size limits. Any input or even pointing me to a KB article from MS would be greatly
