[Dovecot] Can't connect to my mail server (postfix + dovecot, IMAP) with Thunderbird

[GASPARD Kévin]

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.
