[Dovecot] User unknown in local recipient table? Dovecot LDA/Postfix

[Yu Chen]

This probably is a postfix problem, but I think there are lots of postfix 
experts/users on this list, and have heard a lot good things about this 
list, so I am just giving it a try. Thanks in advance!

I am using dovecot-1.0.0-8_56.src.rpm downloaded from atrpms.net, and 
rebuilt from it(rpmrebuild ...). Postfix is 2.4.3.

I followed documents at http://wiki.dovecot.org/LDA and LDA/Postfix, and 
used passwd-file (created /etc/passwd.dovecot file) both as password 
Database and User database. I can send emails, but not receiving, keep 
getting the "User unknow error". Do I need to change the 
"local_recipient_map" in main.cf, and if so, how?

Here are some related configuration:
