Someone has connected to the POP3 server on GMS and issued a LIST command. However, the user has not logged on yet, so GMS has rejected the command. This might have happened because:
- Someone is attempting to gain access to your system without authority;
- The POP3 mail client is not working correctly.
In this case session Undefined was processing a connection from IP address Undefined and received the command
. GMS has rejected the command with
-ERR Access denied
GMS has identified the incorrect command and handled it. You may wish to contact the person at the IP address Undefined and ask them to contact the vendor of the mail client for an upgrade. Alternatively suggest that they use GMS Webmail.
