dovecot - Feb 2012 - Can't connect to my mail server (postfix + dovecot, IMAP) with Thunderbird

Hi,

I've a problem with Dovecot and Thunderbird. Actually I'm trying to 
setup a virtual host server mail with postfix + dovecot (2.0.9) on 
CentOS 6.2. This is my dovecot -n : http://pastebin.com/wZWAE5Cj (I 
guess the errors are not important, that's just saying there is some 
obsoletes values, I will fix that later until it's not inconvenient to 
setup correctly dovecot).

I've a file to store password (/etc/dovecot/passwd) and when I'm trying 
to connect with telnet to my host on port 143 it works, after I can log 
myself with the command ?a login user at domain.tld passwd? and it works, 
this is the entire output of the telnet connection : 
http://pastebin.com/h10cQVqf but actually when I'm trying to connect 
with thunderbird I've an error about the password and the login, this is 
a screenshoot : http://images.koshie.fr/TB_problem.png and to finish, 
there is nothing into the log... The password and the user are corrects !

Of course, dovecot and postfix are started, this is the netstat -a | 
grep "dovecot" : http://pastebin.com/bwfsS4Tf

If you need more informations tell me.

PS : Excuse me for my bad english, also I'm new with dovecot.

Cordially, GASPARD K?vin

I'm sorry, some one tell me my netstat (on IRC) is useless.

Also my pastes will be destroyed in something like one day, that's 
stupid (that's originally for IRC), so this is the output of my :

dovecot -n : http://pastebin.com/Tewcb7bm
telnet : http://pastebin.com/6gY2puxF
netstat -Nnap | grep "dovecot" : http://pastebin.com/yx2wxfWf

Sorry for the error.
