java程序 收发邮件 fail to connect

[vae819723280]

大家帮帮忙~这是一个小程序，收发邮件的，运行没出错~但是结果是fail to connect，要怎么设置eclipse？还是程序问题？
Jmail：[code=Java]package com.qj.mail;

import java.util.Properties;
import javax.mail.Message;
import javax.mail.Session;
import javax.mail.Transport;
import javax.mail.internet.InternetAddress;
import javax.mail.internet.MimeMessage;

/**
* 用于发送jmail邮件 关联java文件 SMTPAuthenticator.java
* @author 朱志杰
*
*/
public class Jmail {

/**
* 发送jmail
* @param title email标题
* @param content Email内容
* @param hostSmtp 发件邮箱 smtp地址 如：smtp.163.com
* @param hostAddress 发送邮箱地址 如：[e-mail]
* @param hostPwd 发送邮箱密码
* @param toAddress 接收邮箱地址 如：[e-mail]
*/
public void sendMail(String title, String content,String hostSmtp,String hostAddress
,String hostPwd,String toAddress) {
// String hostSmtp = "smtp.163.com"; // 邮箱smtp
// String hostAddress = "[e-mail]"; // 发件箱地址
// String hostPwd = ""; // 发件箱密码
// String toAddress = "[e-mail]";// 收件箱地址
try {
String mail = content;
// properties里面包含发送邮件服务器的地址
Properties mailProps = new Properties();
mailProps.put("mail.smtp.host", hostSmtp);
mailProps.put("mail.smtp.auth", "true");
SMTPAuthenticator smtpAuthenticator = new SMTPAuthenticator(hostAddress,
hostPwd);
Session mailSession = Session.getDefaultInstance(mailProps,
smtpAuthenticator);
MimeMessage message = new MimeMessage(mailSession);
message.setFrom(new InternetAddress(hostAddress));
message.setRecipient(Message.RecipientType.TO, new InternetAddress(
toAddress, false));
message.setSubject(title);
// System.out.println("准备发送邮件！！！");
message.setText(mail);
Transport.send(message);
} catch (Exception exc) {
exc.printStackTrace();
}
}

public static void main(String[] args) {
Jmail aa = new Jmail();
aa.sendMail("朱志杰标题","朱志杰内容","smtp.163.com","[e-mail]","密码","[e-mail]");
System.out.println("Well Done!");
}
}
[/code]
SMTPAuthenticator：

package com.qj.mail;

import javax.mail.Authenticator;
import javax.mail.PasswordAuthentication;

/**
 * 用于Jmail返回邮箱账号和密码的校验(在这里被Jmail类所用)
 * 
 * @author 朱志杰
 * 
 */
public class SMTPAuthenticator extends Authenticator {
	private String name = "";
	private String password = "";

	public SMTPAuthenticator(String name, String password) {
		this.name = name;
		this.password = password;
	}

	public PasswordAuthentication getPasswordAuthentication() {
		return new PasswordAuthentication(name, password);
	}

}

会不会是代理没有设置？

[老猫的TOM]

	public void sendMail() throws Exception {

		Properties props = new Properties();// 创建属性对象
		props.put("mail.smtp.host", getHost());// 设置smtp服务器地址
		props.put("mail.smtp.auth", "true");// 设置服务器smtp需要验证
		Session session = Session.getInstance(props, null);// 创建新邮件并群发
		// Session session = Session.getDefaultInstance(props);
		// session.setDebug(true);
		MimeMessage message = new MimeMessage(session);// 创建过程对象
		message.setFrom(new InternetAddress(getFromAddr()));

		message.addRecipient(Message.RecipientType.TO, new InternetAddress(
				getToAddr()));
		message.setSubject(getTitle());// 设置主题
		Multipart multipart = new MimeMultipart();
		BodyPart contentPart = new MimeBodyPart();
		contentPart.setContent(this.getSendtext(), "text/html;charset=GBK");// 设置信件内容
		multipart.addBodyPart(contentPart);
		if (getAttachPath() != null && getAttachName() != null) {
			BodyPart attachmentPart = new MimeBodyPart();
			DataSource source = new FileDataSource(getAttachPath());
			attachmentPart.setDataHandler(new DataHandler(source));
			BASE64Encoder enc = new BASE64Encoder();
			attachmentPart.setFileName("=?GBK?B?"
					+ enc.encode(getAttachName().getBytes()) + "?=");
			multipart.addBodyPart(attachmentPart);
		}
		message.setContent(multipart);
		message.saveChanges();
		Transport transport = session.getTransport("smtp");
		transport.connect(host, getUsername(), getPassword());
		transport.sendMessage(message, message.getAllRecipients());
		transport.close();
	}

你的SMTP 端口 开了没 或者你电脑的SMTP服务禁用了？
