I think postfix/mysql/dovecot is a great setup. I don't see any reason to switch from Centos. Centos is a very solid OS being basically Red Hat Enterprise. If you like the Debian way of doing things, I personally use Ubuntu Dapper drake server. It's a little more lean than Red Hat and let's you choose what you want to run (do a netstat after install and you'll find nothing listening), but with the brilliant apt package manager things are a piece of cake. Ubuntu gives you more up to date packages than Debian stable, and you get release cycles of six months rather than something that's constantly changing like Gentoo. However, I don't want to flame any distro. I've pretty much run them all and you just need to find what's best for you. If you know and like Centos, you don't really need to change.
