Overview

You may receive a bounce back email when a user performs certain actions, like registering for a course. These emails might look like this:

Delivery has failed to these recipients or groups:
<user email address>
Your message wasn't delivered because the destination email system rejected your message for security or policy reasons. For example, the email address might only accept messages from certain senders, or it might not accept certain types of messages, like those larger than a specific size.
