I run Postfix 2.6.7 in a similar fashion (virtual domains/users/etc) and it works fine on CentOS 5.5 (even with SELinux enabled). Dovecot on the other hand threw up some errors in /var/log/audit/audit.log so I had to make a custom SELinux module to get it to work properly. Other than that you should be set.
