Thanks for your advise.
I had already tried it.


It works on SSL (port 993).
It doesn't works on port 143 with TLS.
Doing some change on ssl in about:config of thunderbird gave me differents logs :
Jan 16 17:53:27 imaptest imap[35698]: accepted connection
Jan 16 17:53:27 imaptest imap[35698]: imapd:Loading hard-coded DH parameters
Jan 16 17:53:27 imaptest imap[35698]: SSL_accept() incomplete -> wait
Jan 16 17:53:59 imaptest imap[35698]: EOF in SSL_accept() -> fail
Jan 16 17:53:59 imaptest imap[35698]: STARTTLS negotiation failed: [10.1.45.1]


Maybe it can help you?!
