If a user attempts to send a message to a Distribution List (DL), the originator of the message may receive the following non-delivery report (NDR):

From: System Administrator
Sent: Tuesday, November 16, 1999 4:26 PM
To: <Originator of message>
Subject: Undeliverable: Check this out!

Your message did not reach some or all of the intended recipients.

Subject: Check this out!
Sent: 11/16/99 4:26 PM

The following recipient(s) could not be reached:

EVERYONE_ALL_DL on 11/16/99 4:26 PM
The content length of the message is too long for the recipient to take delivery

The application log also shows an Event ID 290. There are no message size restrictions on the MTA or user mailbox.


This is caused by a message size limit placed on the DL. It is a common practice to put a message size limit on large DLs to prevent users from sending large attachments to many people, thus overburdening the network and delaying mail flow.
