What is alert 8105?
A remote system issued a VRFY command to GMS. GMS has searched the user database and could not find an account that matches so it has responded that there is no match for the string.
In this case session Undefined was processing a connection from the server/client at Undefined when it received the command
so GMS responded with
552 String does not match anything.
This problem is most likely to be caused by someone who is attacking your system in an attempt to find a weakness. This potential attack has been identified by GMS and ignored. To find out why this is being done, contact the owner of the IP address Undefined and ask them.
