Okay. There's a few problems with running a mail server from home. The primary problem is one of network ip, more than likely, you don't have a static ip, and if you do happen to have a static ip, if it's not within an acceptable ip block, your mail server is gonna get banned by several of the larger ISPs (AOL and it's derivatives, wmconnect, etc. and Earthlink, right off the top of my head, to name a few) so you won't be able to send mail to anyone on those networks from your mailserver. I'm telling you this from personal experience, so be prepared for it.
Secondly, the biggest problem with new sysadmins setting up email for the first time is inadvertantly setting up an open relay. I've done it, everybody that's ever set up a mail server has done it at one time or another. If you set up an open relay, spammers will move in, set up residence and use your box for a spamming fiesta. You will get some of the nastiest emails in the world from hardworking sysadmins questioning your parentage and your predilection for bestiality.
Thirdly, there is no third point.
If you're dead set on setting up an email server, I'd suggest Qmail as it has, iirc, the best security record. Incidentally, qmail's creator, DJ Bernstein, has US $500 for you if you can find a security hole.
Several distributions have prepackaged versions of Qmail, but it would be best if you downloaded the source and built it from scratch.
Dave Sill, author of Life with qmail has also authored a book The qmail Handbook which can be had from Amazon for under $10US.
