There's no config knob to turn to do thing.  However, it is simple
to hack the code a bit.  In logging.c, you will see the following:

    /* Pipes are all setup, send message via sendmail. */
    (void) fprintf(mail, "To: %s\nFrom: %s\nSubject: ",
        def_str(I_MAILTO), user_name);

You could just replace user_name with "sudouser at mydomain" (including
the double quotes).
