The FOLDER utility is used by the PMDF DELIVER utility to place
    mail messages in a user's VMS MAIL mail folder. Read and write
    privileges are required to place a message in the mail folder
    of another user. This utility is intended primarily for use by
    DELIVER; system managers and users are unlikely to find it useful
    in and of itself.

    All of the specified input files will be placed in the specified
    mail folder as a single mail message. Unless the /BLANK qualifier
    is specified, there will be no separators placed between each
    file as delimiters.

    The optional folder-name parameter specifies the name of the VMS
    MAIL folder in which to place the message. If not supplied, then
    the message will be placed in the NEWMAIL folder.

    If the option mail-file-spec parameter is not specified, then the
    default mail file for the specified user will be used. If /MM is
    used this parameter is meaningless and is not allowed.
