Postfix not delivering to dovecot for local users (delivering to default user mail)


I am currently in the process of setting up a postfix/dovecot mailserver on Centos 5 as a replacement for an aging exchange server.

I have managed to get postfix to send to external addresses with no issues however when I attempt to send an email to an address which should be handled by dovecot (as it is a local user). I find that the email is just thrown in the users inbox for the default user mail system which is on *nix (poorly described I know).

So currently I can send messages to local users but cannot check them via IMAP/dovecot. I have to check them via mailx -u USERNAME where they display fine.

It appears that all the local user emails are just bypassing dovecot as there are no records.

Also dovecot is setup with MySQL as a backend (for the mailboxes I believe) and I can browse mailboxes in /vmail/DOMAIN/USER/ (they are maildir mailboxes apparently). I havent posted the config for dovecot because there are only small changes which enables the MySQL side of things which appears to be working. However if needed I can post this.

If anyone can shed some light on what im possibly doing wrong then it would be greatly appreciated. As you can probably tell this is my first real attempt at anything to do with mailservers



P.S: in the postfix config file below is just redirected to the local machine in /etc/hosts
