In a similar vein but open source is ssmtp. It's a simple MTA that hands off the dirty work of sending e-mail to a real mailserver, and can be configured to use your existing SMTP server as a bounce point, or if you're running a personal server, your gmail account.
I'm not clear as to why anyone thought this tool was needed or was any more complex than a simple script. This functionality is built in to most platforms.
