求教关于JAVAMAIL发邮件的问题~100分

这是我收集的请参考一个简单的关于Email发送的javabeanpackage bag.mail;

String from = "your name";

mbp.setText(body);
Multipart mp = new MimeMultipart();
mp.addBodyPart(mbp);
message.setContent(mp);
message.setSentDate(new java.util.Date());
Transport transport = session.getTransport("smtp");
transport.connect("smtp.163.net",username,password);
transport.send(message);

  message.setSubject("Test from JavaMail.");
  message.setText("Hello from JavaMail!");  Transport.send(message);
%>这是最简单的例子.

发件人和收件人要同样的smtp服务器吧~~我给自己发能发的了，给别人就不行了

我怎么改了不同邮局的信箱，用发件人的smtp也发不出去呢？

  props.put("mail.smtp.host", "smtp.0451.com");

  message.setFrom(from);
  InternetAddress to = new InternetAddress("[email protected]");
  message.addRecipient(Message.RecipientType.TO, to);

  message.setSubject("Test from JavaMail.");
  message.setText("Hello from JavaMail!");  Transport.send(message);
%>这样没有问题，我把[email protected]换成任何一个就提示地址无效！！

你发不出去邮件除了楼上说的那种情况外，还有一种情况是像21cn等smtp服务器只有你交费了才能使用它的邮件服务，否则你只能从21cn的网站上登录，我有完整的javamail程序源代码，其实javamail的难点在收。

你做了身份验证处理了吗？现在SMTP服务都要验证的。加一点点代码就可以了
www.cn-java.com 上有专门的说明，在JavaMail专题里。
