Answer
The auto responder was going to send a response to an incoming email but has discovered that there is no destination address.
In this particular case session Undefined was receiving an email from IP address Undefined. The email was apparently from Undefined to Undefined, the response has been redirected to Undefined.
This is not a problem with GMS but it is a problem with the sending mail server or client. No action is required by you.
