各位大侠！如果在系统中实现收发邮件啊？？
各位，如何在管理系统中实现邮箱的程序啊！！
[解决办法]
package duba.mail;
import java.util.Properties;
import javax.mail.*;
import javax.mail.internet.*;
public class MailExample {
public static void main (String args[]) throws Exception {
String host = "smtp.163.com"; //发件人使用发邮件的电子信箱服务器
String from = "1@163.com"; //发邮件的出发地（发件人的信箱）
String to = "2@qq.com"; //发邮件的目的地（收件人信箱）
// Get system properties
Properties props = System.getProperties();
// Setup mail server
props.put("mail.smtp.host", host);
// Get session
props.put("mail.smtp.auth", "true"); //这样才能通过验证
MyAuthenticator myauth = new MyAuthenticator("user", "pwd"); //user是发送邮件的用户名，pwd密码
Session session = Session.getDefaultInstance(props, myauth);
//session.setDebug(true);
// Define message
MimeMessage message = new MimeMessage(session);
// Set the from address
message.setFrom(new InternetAddress(from));
// Set the to address
message.addRecipient(Message.RecipientType.TO,
new InternetAddress(to));
// Set the subject
message.setSubject("测试程序！");
// Set the content
message.setText("这是用java写的发送电子邮件的测试程序！");
message.saveChanges();
Transport.send(message);
}
}

例二：

setSmtpHost(getConfig.mailHost);//如果没有指定邮件服务器,就从getConfig类中获取
createMimeMessage();
}

setSmtpHost(smtp);
createMimeMessage();
