I have heard from what I would reliably consider good sources that this
tutorial is wrong. Please proceed with caution and use multiple howtos,
here are just a couple:
http://www.securitysage.com/guides.html (this one is very thorough and
very good.)
http://www.high5.net/howto/ (another very good resource. used by most
people I speak with)
http://www.sweeney.demon.co.uk/pfix_imap_virtual.html (a good reference,
not entirely accurate, but should work well)
www.postfix.org (can't go wrong here, tons of documentation)

One thing to remember, unless you change this:
home_mailbox = <dir>
Postfix defaults to placing mail in ~/Maildir/ so make sure you change
this. Or postfix won't know where to deliver it.
Also this may seem obvious, but it is just a check. You do know that
Postfix is just a SMTP (MTA) server not a POP3/IMAP (MUA) right?
>How do I get one there?
I don't use Gentoo, but in BSD's you can in /usr/share/skel place
dirs/files that you want propagated to users directories once you add
them.
>How do I find out if I have another MTA (is that what they are called?)
>that could interfere with postfix?
Again, I don't use Gentoo, but in BSD's there is a command netstat -n -f
inet that will tell you what is listening where. You can also do a ps
-acux and see if you see any other smtp servers in there, sendmail being
one that I am thinking of.

I don't know what these are.

You can either point Apache to your mail server or install mini-sendmail
(i think that is the name, but it is a stripped down version of sendmail
that works brilliantly with Apache, especially nice for chrooted
environments).

This is like asking what is your favorite editor, vi or emacs? It is a
religious debate, one purely based off personal preference. I have
worked with both and find Postfix to be a lot easier, quicker to
install. It is also very intuitive for me. But I would recommend
trying both if you think it is necessary. One other thing that I find
rewarding about Postfix, is that the developer (Wieste Vienma (sp?)) is
a great resource and answers lots of mail on the mailing lists. I
haven't heard such great things about the Qmail developer. But again,
this is what _I_ look for in products (read, personal preference)
