Ok, I'm just really stuck. Where I'm at is, I've done the complete install, and got it working with the exception that whenever I send emails to an account, it is accepted by the server but it just dissappears. Basically, all new emails are getting dumped. I'm really, really stuck.

Here is the tails of /var/log/messages and /var/log/maillog
