Hello, I tested well with: "cipher preference: server" , the openssl_options: "+cipher_server_preference" , but I hadn't done enough tests. Indeed, they correctly describe the order of the encryption algorithms, it works. Thank you very much for your help. Regards -Message d'origine-

[exim] Define preferred encryption algorithms

2019-10-11 Thread jmedard--- via Exim-users
Hello, More and more Internet security diagnostic tools (such as Immuniweb and Hardenize) specify that mail servers should be able to offer their preferred encryption algorithms. They consider it a security risk if the server must not be configured to select the best-available suite. They
