It's not working because your IP address has been temporarily rate limited. To get around it would require using a different IP address.
i'm testing an another computer but it has failed :

Basically, you'll need to open a network socket, and then send the email commands over it (just Google the email RFC for the specs). Alternately, there are probably some libraries out there that you can use, too.
