I have the following two settings in my "10-ssl.conf" file

# SSL protocols to use ssl_protocols = !SSLv2

# SSL ciphers to use ssl_cipher_list = ALL:!LOW:!SSLv2:!EXP:!aNULL

I have seen different configurations while Googling. I am wondering what the consensus is for the best settings for these two items. What do the developers recommend?

Not a developer, but I use the settings from https://cipherli.st, namely:

ssl = yes
ssl_cert = </etc/dovecot.cert
ssl_key = </etc/dovecot.key
ssl_protocols = !SSLv2 !SSLv3
ssl_cipher_list = AES128+EECDH:AES128+EDH
ssl_prefer_server_ciphers = yes # >Dovecot 2.2.6
ssl_dh_parameters_length = 4096 # >Dovecot 2.2

Thanks!
