I recommend following this tutorial by Christoph Haas: http://workaround.org/articles/ispmail-etch/ which will soon be updated for Debian 5.0 Lenny. There's a community around it, reached through a mailing list, which gives you a fairly good backing when you need help. The tutorial is used by a lot of people so it's well proven and in my experience can be relied upon to just work. The author is a Debian developer. This was first recommended to me on a Debian IRC channel when I was trying to piece all the mail server packages together by myself, probably by Cafuego I think, for which I'm continually grateful. There are other such tutorials too though I've not tried them.
