Answer 1

你看看这个位置怎么了
SendMail.java:49

Answer 2

直接粘贴大段代码，和异常堆栈，不容易查看，请做详细点的描述。

建议楼主用commons-email吧，三个jar包（activation.jar，commons-email-1.0.jar，mail.jar），去官方网站下载即可，附我测试成功的代码：

Answer 6

49行就是这个代码：Transport.send(message);indeed说的那个方法现在试验不了，公司下载不了东西 只能回家再试了。

Answer 7

163是不行换了个sina的也不好用

Answer 8

indeed那个方法也试了  还是验证失败。。
疯了

Answer 9

[email protected]你有权限使用smtp吗，你在foxmail试试outlook也行，不是随便一个163账户就行了，
1。积分要够
2。老会员我认为是这个原因，没多看大概一看猜是这个问题。

private String pwd; public SendMail(String userName, String pwd) {
super();
this.userName = userName;
this.pwd = pwd;

String subject = "测试"; Properties props = System.getProperties();
props.put("mail.smtp.auth", "true");
props.put("mail.smtp.host", "smtp.163.com");
SendMail sa = new SendMail("newsunyujia", "密码");
Session sess = Session.getInstance(props, sa); Message msg = new MimeMessage(sess);
msg.setFrom(new InternetAddress(from));
msg.setRecipients(Message.RecipientType.TO, InternetAddress.parse(

msg.setSentDate(new Date());
msg.setText("你好");
