Answer
A message has been sent to an auto responder in GMS. GMS checked the logs and found that it has already sent the auto response message to this address within the configured time frame, so another one is not required.
In this particular case session Undefined was receiving an email from IP address Undefined. The email was apparently from Undefined to Undefined. Because GMS has already received a message from Undefined, no autoresponse message was sent.
This is the correct action so no action is required by you.
