Postfix not delivering mail received

I have read up on many posts to do with postfix not delivering emails and have posted this on someone elses thread so im starting my own for help

I am running debian lenny from the perfect server setup, i have followed the tutorial for setting up postfix mysql and virtual users and have 7 sites running on my server. (NO ispconfig)

I CANNOT RECIEVE EMAILS FROM OUTSIDE THE SERVER. the mail log says user unknown and bounces all email attempts.

all my sites can send emails to each other, to gmail,hotmail,yahoo etc but none of the accounts will recieve.

The emails are arriving at the server but my server is rejecting them as user unknown

i have checked main.cf for example.com as i have it in mysql virtual db and it is server1.example.com

here is the result of netstat -tap

PHP:
