I found one connecting mail server who consistently caused TLS Handshake failures. Using ssldump I could see that our Xmail server was always trying to negotiate the TLS 1.2 ciphers according to the client sequence, which had a strange ordering: some weaker ciphers were listed ahead of the better ones.
Is there a setting, perhaps in /etc/xmail/server.tab, which will tell our Protector Server to use its own cipher sequence order?
Doing some research, I have found similar settings for other servers, called something like SSLHonorCipherOrder or "ssl_prefer_server_ciphers" or "tls_preempt_cipherlist" or but I don't know if they work here.
