我换了很多种写法都不行  
还尝试了网上的删除SSLv3的那种方法，也不行  
在本地是telnet得通的  
防火墙也放行了465端口  
不是多线程原因，已经试过了  
代码附在下面，求大神指点

你是不是少了一些信息
  1. // 创建Properties 类用于记录邮箱的一些属性
  2. Properties props = new Properties();
  3. // 表示SMTP发送邮件，必须进行身份验证
  4. props.put("mail.smtp.auth", "true");
  5. //此处填写SMTP服务器
  6. props.put("mail.smtp.host", "smtp.qq.com");
  7. //端口号，QQ邮箱端口587
  8. props.put("mail.smtp.port", "587");
  9. // 此处填写，写信人的账号
  10. props.put("mail.user", "[email protected]");
  11. // 此处填写16位STMP口令
  12. props.put("mail.password", "xxxxxxxx");
