You're more than off base. Your understanding is thin and full of gaps. I'm
surprised that you want to do this much work of installing a mail server, installing
a web server, installing BIND, etc., when it seems that you don't have the knowledge
of even how to configure those things once they are installed. I'm not being
critical here, just assessing your ability to do what you're attempting.

I think you'd be better off using a server that is already a functioning web server
with mail server, etc. Then you could concentrate on learning how to install and
configure SquirrelMail.
