TLS config check

[SW]

Hi All

First the essentials:

dovecot --version: 2.2.15

/usr/local/etc/dovecot/conf.d/10-ssl.conf:

ssl = required

ssl_cert = 
</usr/local/openssl/certs/mail.domain.com.chained.dovecot.ecdsa.crt

ssl_key = </usr/local/openssl/certs/mail.domain.com.ecdsa.key

ssl_protocols = !SSLv2 !SSLv3

ssl_cipher_list = 
HIGH:EECDH+ECDSA+AESGCM:EECDH+aRSA+AESGCM:EECDH+ECDSA+SHA384:EECDH+ECDSA+SHA256:EECDH+aRSA+SHA384:EECDH+aRSA+SHA256:EECDH:EDH+aRSA:ECDHE-RSA-AES256-SHA:+DHE-RSA-AES256-SHA:!AES256-SHA256:!AES256-GCM-SHA384:!CAMELLIA256-SHA:!AES128:!CAMELLIA128:!aNULL:!eNULL:!LOW:!3DES:!MD5:!EXP:!PSK:!SRP:!DSS:!RC4:!SEED:+AES256-SHA

ssl_prefer_server_ciphers = yes

I would really appreciate it if someone could tell me if my config is 
super secure? I run the following email clients:

K9 on Android 4.4.2
Thunderbird 31.4
Outlook 2010

I'm interested to know if the config I have is secure and that my cipher 
list is acceptable. I'm also keen  to hear thoughts on my config in 
respect of Forward Secrecy and the SSLv3/POODLE attack.

Thanks!
