/sys$common/syshlp/helplib.hlb MAIL Command, Qualifiers, /PERSONAL_NAME  *Conan The Librarian (sorry for the slow response - running on an old VAX)

       /PERSONAL_NAME=name
       NOPERSONAL_NAME

    Specifies the personal name to be used when sending a message.
    Use quotation marks around the personal name to include more than
    one word or to print in lowercase letters.

    This qualifier does not override the default personal name
    specified by the SET PERSONAL_NAME command; the personal name
    is only changed for the current message.The /NOPERSONAL_NAME
    qualifier sends a message with a null personal name field.
