A POP3 client has successfully logged on to GMS and issued a command requesting details of a particular message. However, the message requested is not available.
In this case session Undefined was processing messages for the account Undefined@Undefined with a client at the IP Address at Undefined. The client issued the command
and GMS responded with
-ERR no such message, only Undefined messages
This is not a problem with GMS. To resolve the problem you will need to contact the manufacturer of the mail client at Undefined for an upgrade to an Internet Mail Standard client or suggest that the user uses GMS Webmail instead of a POP3 client.
