Answer
GMS connected to a remote system to send an email message. While the connection was successful, the remote server indicated that it was temporarily unavailable (with a 4xx SMTP response).
In this case, session Undefined was was processing a message to be delivered to the server Undefined (IP address Undefined). The local folder name is Undefined. GMS sent the command
HELO Undefined
and got the response
Undefined
There is no problem with GMS and it will automatically reschedule the message, so no action is required by you. However, you may wish to investigate the problem with the remote server.
