Answer
A remote system (client or server) has negotiated a secure channel with GMS for the delivery of email. This means that the email message between that system and GMS will be encrypted so that no third party can spy or copy the message while it is in transit. If GMS needs to relay this message (e.g. if the message was sent by someone internally to someone external), GMS Secure Socket Layer can be configured to require that the onbound transmission is also over a secure channel.
In this case, session Undefined has established a secure connection with the remote client or server at the IP address Undefined.
