Hmm, that makes sense.  I assumed that people use an email address at a
mail server that is always connected.  So I thought that the only
problems would arise when a server was temporarily down.  I didn't know
that you could recieve mail _reliably_ directly at your own computers mail
server if you are connected intermittently.

So what you are saying then is: that I could go to one of those dynamic
DNS servers, set up an account, with my computer automatically
updating the address of my IP everytime I connect, and then I could give
out an email address for my machine and receive mail directly?????

Hmmm, that is a good reason to use a smarthost indeed.
