package javamail;

import java.util.*;
import java.io.*;
import javax.mail.*;
import javax.mail.internet.*;

public class SendJavaMail{

public static void main(String[] args){

try{
Properties mailProps=new Properties();
mailProps.put("mail.smpt.host","smtp.tom.com");

Session mailSession=Session.getDefaultInstance(mailProps);

Transport transport=mailSession.getTransport("smtp");//创建Transport，使用smtp协议

MimeMessage message=new MimeMessage(mailSession);

InternetAddress fromAdd=new InternetAddress("[e-mail]");
InternetAddress r[] = new InternetAddress[1];
//System.out.println(fromAdd.getAddress());
message.setFrom(fromAdd);
r[0] = fromAdd;
InternetAddress[] toAdd =InternetAddress.parse("[e-mail]");
message.setRecipients(Message.RecipientType.TO,toAdd);
message.setSubject("Hello from Java Mail!");
message.setText("Hello!\n"+"It is I,Senor Coffee Bean!I bring you greetings. \n"
+ " from the java mail API! . \n"+
" Senor Coffee Bean,Esp.\n");
message.saveChanges();
transport.connect("smtp.tom.com","******","******");
System.out.println("====connected!====");
transport.send(message);
transport.close();
}catch(Exception exc){
System.out.println(exc.getMessage());
exc.printStackTrace();
}

}
}
这是源代码，运行时send（）方法一直报错，请各位帮忙解决！

up一下，有谁能解答！

认证问题，你需要一个传密码认证的类
需要认证的邮件这句话是不够的：transport.connect("smtp.tom.com","******","******");
认证的类是继承自javax,mail包中的一个类，类名我忘了，你自己搜索一下，满街都是！
