[Pound Mailing List] SSL Parameter

Hello,

i just made a test via ssllabs.com. And i got a grade F for my SSL
connection.

The issues are :

This server supports insecure Diffie-Hellman (DH) key exchange parameters.
Grade set to F.
This server supports 512-bit export suites and might be vulnerable to the
FREAK attack. Grade set to F.
This server is vulnerable to the POODLE attack. If possible, disable SSL 3
to mitigate. Grade capped to C.
This server accepts the RC4 cipher, which is weak. Grade capped to B.

My pound.cfg is this in the https section:

ListenHTTPS
    HeadRemove "X-Forwarded-Proto"
    AddHeader  "X-Forwarded-Proto: https"
    Address    0.0.0.0
    Port       443
    Cert       "/etc/ssl/mydomain.com/mydomain.com.pem"
    Ciphers
 "DHE-RSA-AES256-SHA:DHE-DSS-AES256-SHA:AES256-SHA:DHE-RSA-AES128-SHA:DHE-DSS-AES128-SHA:AES128-SHA:KRB5-DES-CBC3-MD5:KRB5-DES-CBC3-SHA:EDH-RSA-DES-CBC3-SHA:EDH-DSS-DES-CBC3-SHA:DES-CBC3-SHA"/"ALL:!SSLv2:!SSLv3"
    Service
        HeadRequire "Host: mydomain.com"
        Redirect "https://www.mydomain.com"
    End
    Service
        BackEnd
            Address 127.0.0.1
            Port    6081
        End
    End
End

Can anyone advise what i need to change to get a better rating and make it
more secure?

thanks,

Daniel
