What is alert 8457?
A message was sent to a list for posting to all the list members. The message was not posted because any message from this sender has been banned. Banning certain senders from posting to the list allows the list owner to stop malicious senders posting to the list while still leaving the list open to the public.
In this case, request Undefined was going to post a message from Undefined to all the members of the list Undefined.
