Currently I have the following set in Dovecot on my server:
ssl_cipher_list = AES128+EECDH:AES128+EDH
When I connect with Thunderbird 31.4 I see the following in the log:
When I connect with K9 mail (latest version) on Android 4.4.2 I see:
How can I get K9/Android to connect using GCM (ie ECDHE-ECDSA-AES128-GCM-SHA256)?
I had a look at:
and Android 4.4.2 does support:
0xc02b) Forward Secrecy
So why won't it use the GCM cipher? Is this a K9 mail limitation?
