58         Transport ts = session.getTransport();
59         //3、使用邮箱的用户名和密码连上邮件服务器，发送邮件时，发件人需要提交邮箱的用户名和密码给smtp服务器，用户名和密码都通过验证之后才能够正常发送邮件给收件人。

63         MimeMessage message = new MimeMessage(session);
64         //指明邮件的发件人
65         message.setFrom(new InternetAddress("×××××××××××@163.com"));
66         //指明邮件的收件人
67         message.setRecipient(Message.RecipientType.TO, new InternetAddress(recipient));
68         //邮件的标题
69         message.setSubject(Subject);
70         //邮件的文本内容
71         message.setContent(content, "text/html;charset=UTF-8");
