为 Microsoft Azure 云为 DDNS 添加的 DHCP 客户端 hook 示例
用于 Microsoft Azure 云动态 DNS (DDNS)的
DHCP 客户端 hook 示例已添加到 dhcp 软件包中。管理员现在可以轻松启用此 hook，并使用 DDNS 服务器注册 Red Hat Enterprise Linux 客户端。(BZ#1321945)
Postfix 现在支持由用户控制的 TLS配置
在这个版本中，postfix 提供配置选项来更加精确地控制传输层安全(TLS)协议版本。例如，您可以在启用
TLS v1.2 时禁用 TLS v1.1。要做到这一点，请在 main.cf 文件中添加以下行：
smtpd_tls_mandatory_protocols = !TLSv1.1
smtpd_tls_mandatory_protocols = !TLSv1.1
