Q: Why do I receive email bounces that delivery has failed to these recipients or distribution lists?

• I am an MIT email user and when I send email to a moira list I receive the message: Delivery has failed to these recipients or distribution lists?

Context

• In using moira lists, if a username, list or string has any members that are no longer valid, you will receive these bounces. Everyone on the list except those who may no longer have a valid email address will receive the email.

Answer

• Ensure your moira list memberships are up-to-date to avoid future bounces.
