CentOS - Aug 2011 - dovecot problem -- not deleting messages from server after downloading them

I recently installed CentOS 6.0 and Dovecot 2.0.

My problem is that, when I download emails to my laptop (running 
Thunderbird), the emails are NOT deleted from my server.  They stay 
there and are downloaded again and again.  8-(

The "Leave messages on server" option in Thunderbird is not checked.

I have several laptops that used to work when I ran CentOS 5.6 / Dovecot 
1.x.  I haven't changed their configuration and they all have the same 
problem.

Here's a sample (personal data removed) of /var/log/maillog when I 
download messages (note the "del=0/487" on the 2nd line):

Aug 13 14:28:54 chasserver dovecot: pop3-login: Login: user=<centos>, 
method=PLAIN, rip=192.168.0.2, lip=192.168.0.27, mpid=18393, TLS
Aug 13 14:29:28 chasserver dovecot: pop3(centos): Disconnected: Logged 
out top=0/0, retr=487/2134628, del=0/487, size=2126323

My "dovecot -n" output is below.

Thanks,
Charlie

According to the POP3 protocol messages are first marked to be deleted
by the server on DELE command, but only really deleted in the UPDATE
state, means after the QUIT command.

I solved the problem by disabling SELinux. Not sure why that fixed it, 
but it did make me dislike SELinux just a little bit more. LOL
