求助！！！
为什么 sendTo 的电子邮件址址用自己本机的地址就行也可以发送到本机，但如果用一般的电子邮件地址如： [email]xxx@xxx.com[/email] ，就出现如下错误：
import javax.mail.*;
import javax.mail.internet.*;
import javax.activation.*;
import java.util.*;
public class SendMail {
private String sendTo = "my.goto.net";//本机的，测试其他的是用[email]xxx@xxx.com[/email]
private String sendFrom = "[email]my@my.com[/email]";
private String subject = "Hello,This is a email";
public SendMail() {
}
public void send(){
try{
Properties props = new Properties();
Session sendMailSession;
Store store;
Transport transport;
sendMailSession = Session.getInstance(props, null);
props.put("mail.smtp.host", "my.goto.net");
Message newMessage = new MimeMessage(sendMailSession);
newMessage.setFrom(new InternetAddress(this.sendFrom));
newMessage.setRecipient(Message.RecipientType.TO, new InternetAddress(this.sendTo));
newMessage.setSubject(this.subject);
newMessage.setSentDate(new Date());
newMessage.setText("this is content,succeed.");
transport = sendMailSession.getTransport("smtp");
transport.send(newMessage);
}catch(AddressException e){
System.out.println("-----------address exception-----------");
e.printStackTrace();
}catch(MessagingException e){
System.out.println("-----------message exception-----------");
e.printStackTrace();
}
}
public static void main(String args[]){
SendMail s = new SendMail();
System.out.println("----------------- start ------------------");
s.send();
System.out.println("----------------- succeed ------------------");
}
}

java的sendmail做的都是relay的转发。如果你用别人的smtp服务器，人家不让你relay就不行了。你可以自己发给自己，说明你的程序没有什么问题。而且你本机的sendmail应给也没有什么问题，不过是打开了relay的设置吧。
