Mail: Auth-SSL-Protocol and Auth-SSL-Cipher headers (ticket #2134). This adds new Auth-SSL-Protocol and Auth-SSL-Cipher headers to the mail proxy auth protocol when SSL is enabled. This can be useful for detecting users using older clients that negotiate old ciphers when you want to upgrade to newer TLS versions of remove suppport for old and insecure ciphers. You can use your auth backend to notify these users before the upgrade that they either need to upgrade their client software or contact your support team to work out an upgrade path.
