Problem is the old os was a RH9 (I know) system, built from source, etc. The new box is staged (CentOS5), postfix installed via YUM and the config was then compared. They were using virtual domains/users, so that part of the config was moved and looks like this;

They use some PHP webmail front end, debugging up and a test login (forced fail since I don't have a valid user/pass) I saw this in the apache log;

On extracting the backups, I do see a userdb file which I can cat and looks like my user info; example;

Before you get too far into config, may I suggest that you upgrade to Postfix 2.8? The version from the CentOS repos is woefully outdated.
Postfix 2.8 for CentOS 5 instructions here:
