An SMTP server definitely sends email. However two problems...

1) If you just copy/pasted the code from that page, the server is
listening on port 1234, while you're trying to connect to port 25.
2) *THAT* server does not actually send email. It's not meant to send
email; the code seem more a simple example of how to use GSever.
