Sorry for chiming in with a related question.

I'm not an experienced OpenSSL user, but managed to create certificates and to make OpenSSL 1.0.2 listen on port 443 for incoming requests. Works great for checking ciphers enabled in browsers. Now, I also want to check ciphers enabled in (mobile) mail clients. I've tried to make OpenSSL listen on port 110 (for POP with TLS) and redirected the client to the OpenSSL server. But when trying to pull mail I can't see any handshake information: > >openssl s_server -cert public.pem -key ca-key.pem -accept 110 -debug > Enter pass phrase for ca-key.pem: > Loading 'screen' into random state - done > Using default temp DH parameters > ACCEPT > read from 0x4c0df0 [0x4c63e0] (11 bytes => 6 (0x6)) > 0000 - 51 55 49 54 0d 0a QUIT.. > read from 0x4c0df0 [0x4c63e6] (5 bytes => 0 (0x0)) > ERROR > shutting down SSL > CONNECTION CLOSED > ACCEPT I'm obviously missing something. Could anyone please enlighten me? Wald
