/LOG=log-list

    Specify what sort of informational message PMDF SEND should
    issue. The log-list is a list of zero or more of the following:
    NONE, ADDRESSES, FILES, MESSAGES, IDS, or ALL. NONE indicates no
    logging, is equivalent to /NOLOG, and is the default. ADDRESSES
    causes one informational message to be output for each specified
    recipient address. FILES causes one information message to be
    output for each input file. MESSAGES produces a summary message
    that indicates how many addresses and files were processed
    successfully. IDS produces an informational message showing the
    contents of the Message-Id: header of the resulting message.
    ALL activates all forms of logging; it cannot be specified
    simultaneously with NONE. /LOG=MESSAGES is the default if /LOG
    is specified without an explicit log-list.
