Note what I asked for.
If you have installed postfix + spamassassin or whatever under CentOS
then presumably you downloaded certain packages
and then made certain changes in config files and perhaps elsewhere.
Therefore it is possible to write a short document just listing
the changes you have made.
It may be a waste of time in your view;
but in my experience this is exactly what I want to read
for my very basic home server needs.

I don't see why not.
That is exactly what I do, in both cases.
The difference in my experience is that apache documentation is much better.

MySQL, LDAP, PHP, etc, are not part of httpd,
but they all seem to me to work well together
without studying the matter in depth.

If I had to read a book in order to install and configure postfix
I would go back to sendmail.

You sound as though you think it is meritorious
for software to be difficult to use.
The task of postfix seems to me fairly easy to understand,
so I don't see why implementing a solution should be that difficult.
