Can Javascript be used to connect with a server with a protocol other than HTTP or FILE? Ideally, I would like to connect to an SMTP server using Javascript.

Not possible due to security constraints in the browser. Can be done in flash or java as far as I know. The upcoming WebSockets won’t help you either.
Your best option is probably to call a script on your server which makes the socket connections to the final destination, i.e the SMTP server and then passes data back to the client over HTTP.
