Answer
GMS Anti-Spam has received a connection from a remote server or client and disconnected. GMS has detected a potential address harvesting attack from the remote system and rejected the connection.
In this case, session Undefined received a connection from Undefined and rejected it.
The IP Address Undefined has previously exceeded the maximum number of receipts allowed per incoming connection and has therefore been denied access to your server for a period of time. Once this period expires they will be allowed access again.
