I would like to use net:smtp to send email through [smtp.gmail.com](http://smtp.gmail.com). The  
problem is that I am behind a proxy, so I need to tell the smtp module  
that it should use the proxy (otherwise it won’t be able to resolve  
[smtp.gmail.com](http://smtp.gmail.com)). How can this be done? There is no obvious way for me to  
specify the proxy. I am using version 1.8.6 of ruby.

What sort of proxy? SOCKS4/5? Something else?
