Thanks Viktor! For anyone who runs into the same/similar problem: it seems no more up-to-date yum package is available for CentOS. I found some pre-compiled packages for CentOS 5 at http://www.linuxmail.info/postfix-rpm-packages/. I was able to do an rpm install of the 2.5.1 postfix package, which automatically upgraded the existing installation.

Read the Postfix release notes. These will highlight any potential compatibility issues and major changes. When upgrading from a release this old, yes you do need to stop Postfix first. Make sure that your binary package installer correctly upgrades the main.cf and master.cf files via "postfix set-permissions upgrade-configuration". Do not undo this by re-installing original main.cf/master.cf files from before the upgrade. For other help on Linux package management, this is not the right forum. -- Viktor.
