I want to use stunnel with TLSv1.2 ciphers but it doesn't work.
I use stunnel 5.07 compiled from source with prefix /opt/stunnel and 
lastest openssl (1.0.1j)

This is my main configuration file:

chroot = /opt/stunnel/var/lib/stunnel/
pid = /stunnel4.pid
**cert = /opt/stunnel/etc/blabla/bla.pem
key  = /opt/stunnel/etc/blabla/bla.key
ciphers = ECDHE-ECDSA-AES256-GCM-SHA384
options = NO_SSLv2
accept  = 993
connect = 143

I had to use one of this ciphers:

When i tried to use imaps connection over stunnel :
root at bla: imtest -a homer -w homer -p 993 -s localhost
SSL_connect error 0
SSL session removed
failure: TLS negotiation failed

if i use a SSLv3 cipher it works.
root at bla: imtest -a homer -w homer -p 993 -s localhost
verify error:num=18:self signed certificate
TLS connection established: TLSv1 with cipher DHE-RSA-AES128-SHA 
(128/128 bits)

Someone have any idea ?
