About IU List delayed delivery notifications

Important:

Indiana University will be transitioning to a single email domain, iu.edu, between now and the end of 2025. For more about the transition, see One Mail. For details about the impact to IU List specifically, see Changes to IU List from the One Mail initiative. For general actions you may need to take, see Prepare for One Mail at IU.

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.
