Definately something wrong here. as root:
grep post install.log
You should see (for Centos 6.3):
Installing postfix-2.6.6-2.2.el6_1.i686
or x86_64 based on architecture. This creates all the postfix default
files. Or install postfix via yum.

All the postfix directories in that howto work, but I did not go with
his 'use my main.cf' I studied it, using postconf and created a script
containing:

============================================
that append above addresses that postconf cannot handle continues. You
can replace it with a single line command; I like the multiline formatting.
If you want more help, let's take it off list. I am at IETF in Orlando
right now, and IEEE 802 next week, then Passover after that, so my
posting speeds will vary.
