    It doesn't, that's what I said. Use Mail::Internet if you want to forge
    the From header. If this is your desire, you're probably a spammer and
    my level of support drops off right here. :)

    I'm not sure I'd call it a wrapper any more than I'd call ANY perl
    script that accesses the shell a wrapper. It opens a filehandle to the
    mail process and prints accordingly.

    No, Mail::Internet is more fine-grained. You provide the mail headers
    you wish to sculpt your message with.

    Uh-oh, spammer alert going off.

    Obviously, yes.

    If you're comfortable with Perl, yes.
