javamail 发邮件的问题

Question

老提示这样的错误：
javax.mail.MessagingException: Could not connect to SMTP host: smtp.163.com, port: 25, response: -1
at com.sun.mail.smtp.SMTPTransport.openServer(SMTPTransport.java:1270)
at com.sun.mail.smtp.SMTPTransport.protocolConnect(SMTPTransport.java:370)
at javax.mail.Service.connect(Service.java:275)
at javax.mail.Service.connect(Service.java:156)
at SendMail.send(SendMail.java:60)
at SendMail.main(SendMail.java:72)
　我的smtp 是这样设置的：
public static final String mailAddress = "[e-mail]";
public static final String mailCount = "xxx";
public static final String mailPassword = "*******";
public static final String mailServer = "smtp.163.com";

错误貌似是提示没有打开服务器，网上有些资料也说是，端口冲突，可我关闭所有的放火墙还是不行，急啊～～～～

我以前的一个例子：
[code="java"]public class Mail01 {

public static void main(String[] agrs){

    Properties props = new Properties();
    props.setProperty("mail.smtp.host", "smtp.sohu.com");
    // 必须有这项设置
    props.setProperty("mail.smtp.auth", "true");
    props.setProperty("mail.debug", "true");

    // Session管理与stmp的链接信息
    Session session = Session.getDefaultInstance(props, new Authenticator(){
        protected PasswordAuthentication getPasswordAuthentication(){
            return new PasswordAuthentication("[e-mail]","XXXX");
        }
    });

    MimeMessage  msg = new MimeMessage(session);
    try {
        msg.setFrom(new InternetAddress("[e-mail]"));

msg.addRecipients(Message.RecipientType.TO,"[e-mail],[e-mail]");
msg.setSubject("测试--群发", "UTF-8");
msg.setSentDate(new Date());
msg.setText("你好，这是一封测试邮件。收到请勿回复", "UTF-8");

        // 使用静态的方法发送信息
        //Transport.send(msg,new InternetAddress[]{new InternetAddress("[e-mail]")});
        Transport.send(msg);
    } catch (MessagingException e) {
        e.printStackTrace();
    }
}

}
