Building a FreeBSD based mail server

[Patrick Baldwin]

I posted a few weeks ago about being interested in building a FreeBSD based
mail server, and got a lot of good input.   In my research since then, I 
found
this:

http://www.purplehat.org/?page_id=4

Which seems to me to be a pretty good guide to building a FreeBSD based 
Postifx/SpamAssassin
mailserver.  However, never having done this before myself, I was 
wondering if anyone here
had any useful comments about this guide, particularly if you think it's 
missing any key points
that will leave me cursing at my monitor late one night. 

I'm currently planning on using FreeBSD 7.0-RELEASE, although I'm 
certainly open to
sugegstions if people think a different version would serve better.
