Welcome Darrell. Here is the summary version:
To install a specific package, such as postfix from a repository that
you are configured to get packages from use:
yum install postfix
To update to the newest version of postfix that is in your configured
repositories use:
yum update postfix
To update everything in repositories that are configured on your machine
use:
yum update
If you are moving between point releases (CentOS 5.1 to CentOS 5.2) use:
yum upgrade
Hope this helps.
Barry
