About IU List delayed delivery notifications

If you email an IU List and receive a delayed delivery notification, the list is likely moderated. When a list is moderated, the email you sent is delayed until it is reviewed, and either distributed to the list or rejected by a moderator. The IU List system generates an email to notify you of the delay.

Email systems interpret the status code of this notification differently. Microsoft's systems will send an email which states, "Delivery is delayed to these recipients or groups" followed by the name of the list. Other email systems may state, "Message distribution: Forwarded" and indicate the email has been forwarded to the list's moderators.
