I don't know of any "off the shelf" solution, I think most people build this functionality themselves. You need to kinow which mail modules you have available on your server. Do you have full control of the server yourself? If not check with your webhosting service. If you have cgi-bin access, you probably already have sendmail, jmail or whatever. You need to find out which and then google for instructions. There's plenty of example scripts out there. You just need to know what your looking for.
