     I would like to rebut a few of the qmail comments, and confirm a
few others.  First, I will start off by saying, I run qmail on many
servers at work, it is one of the more secure mail packages. 
Although, it can be hard to configure.  But
has such a straight through tutorial, you simply follow along.  Using
the QMR tutorial, you will come out, with Virus and Spam protection,
as well as squirrelmail (not the most secure, but easy for the end
user to use).

     All I am saying, is qmail is fine for enterprise mail servers,
its also great for a "live" Internet mail server, and it works.  Might
want to keep it as an option.
