dovecot - Sep 2014 - Trouble viewing Inbox via IMAP Client

Hello, I have been having trouble with this issue for quite some time 
now. Here is my environment: CentOS 6.5, Postfix built with PGSQL 
support, PFA, and dovecot. The problem I am having is that I can send 
and receive mail fine, but when I try to view my Inbox in an IMAP client 
like Thunderbird, I can only view sent mail and trash. Here is the 
result of my dovecot -- version and dovecot -n

--version  2.0.9

dovecot -n
# 2.0.9: /etc/dovecot/dovecot.conf
# OS: Linux 2.6.32-431.el6.x86_64 x86_64 CentOS release 6.5 (Final) ext4
