Ars Technica did a very nice write up on this a little while back. It goes from start to finish, outlining what each piece of software does, why you need it, and the basics on how to set it up.

Note, this is a fairly complex endeavor. There are many, many ways that an incorrectly configured mail server can cause you problems, and unfortunately the benefits when everything is running perfectly are few. If you're just doing this to learn, dive right in, I did and it's certainly an experience. If, however, you plan on using this server for actually hosting the email for you or family/friends, be sure you fully understand how much work is required to set up and maintain a secure mail server, and the many ways things can go wrong.

Again, not saying what you want to do is not a worthwhile endeavor, but be sure to carefully weigh the costs and benefits.
