Answer
A user has attempted to join an incorrect email address to a mailing list in GMS Communication Server. The email address has a dot (as the last character), space, backslash, no user or no domain in the email address. The attempt to join the list will fail and be returned to the sender.
In this case, request Undefined asked for Undefined to join the list Undefined.
This is the correct result, no action is required by you.
