XCON: NDR Sent to Originator Instead of DL Owner

• Microsoft Exchange Server, version 5.5

SYMPTOMS

When you send a message to a distribution list (DL) that is larger than the established message size limit for that DL, a non-delivery report (NDR) is generated and sent back to you, the message originator, regardless of the options set on the Advanced tab of the DL's Properties dialog box. For example, you send a 50-KB message to a DL called Test that has a maximum message size restriction of 25 KB. Also, on the Advanced tab, Distribution List options, the Report to message originator option is disabled (unavailable), and the Report to distribution list owner option is enabled. Instead of the DL owner receiving an NDR as expected, you, the originator,
receive the NDR.

CAUSE

The Report-to-Owner and Report-to-Sender fields that direct this action do not apply to DLs but only to users. When an oversized message is sent to a DL, the message transfer agent (MTA) checks the message size and sends the NDR back before the DL expansion process takes place. In this case, only the default Report-to- Sender function is called, and the NDR goes to the originator.

STATUS

Microsoft has confirmed this to be a problem in Microsoft Exchange Server version 5.5. We are researching this problem and will post new information here in the Microsoft Knowledge Base as it becomes available.
