spoofmessagefile POP Proxy option specifies the file to use for POP3 inbox spoofing. The MMP can imitate a base-functionality POP3 server in case it can't connect to a client's store machine. In such a situation, the MMP creates an inbox for the user and places this one message into it. The format of the message contained in this file should conform to dot-stuffed RFC 822 (including the final '.').
By default, there is no spoof message file.
