我正在尝试使用Java邮件发送邮件。我的邮件服务器仅接受TLSv1.2。我尝试在客户端请求中配置TLSv1.2。但是，在TLS握手期间，我的clientHello始终使用TLSv1。我试图调试下面的握手，

-Dhttps.protocols = TLSv1.2
-Dmail.smtp.ssl.protocols =“ TLSv1.2”
-Djdk.tls.client.protocols = TLSv1.2
我的邮件服务器日志中抛出的错误是

我不知道为什么clientHello总是选择TLSv1而不是TLSv1.2。请帮助我。

答案 0 :(得分：0)
这是 JavaMail 1.5.3 之前的 hardcoded 默认值，因此升级应该可以解决问题（请记住 JavaMail 已被 Jakarta Mail 取代）。
作为一种解决方法，您可以将所需的协议设置为空格分隔列表（如 Ajinkya 所建议的）
properties.put("mail.smtp.ssl.protocols", "TLSv1.2 TLSv1.1");
