In Centos we still have the service command, and it works well with 
services like postfix.  So you start, restart, and stop with:

service postfix start/stop/restart/status

Note that at some point, probably Centos 7, 'service' is going away.

Oh, and:

chkconfig --list|grep postfix

It should be on for all run levels if not:

chkconfig postfix on

Did you install sendmail?

grep sendmail /root/install.log

service sendmail status

chkconfig --list|grep sendmail

Read to Postfix docs on this first then ask questions.  Do a google 
search.  This is something you need to know about.  the campworld howto 
sets you up safe.  If you got all of his stuff done.
