I have a requirement for a stunnel client built with openSSL 0.9.8y to not connect to unpatched servers.
I know this is a simple matter of using  SSL_CTX_clear_options(ctx, SSL_OP_LEGACY_SERVER_CONNECT);

Is there any way of configuring stunnel to clear this option?

If this is the wrong approach, how can I prevent stunnel connecting to unpatched servers?

Thank you for your assistance and look forward to your response.
