Properties props = new Properties();
props.put("mail.smtp.auth", "true"); //这样才能通过验证
props.put("mail.smtp.host", "smtp.sina.com.cn");
Session ssion = Session.getDefaultInstance(props);
ssion.setDebug(true);
MimeMessage message = new MimeMessage(ssion);
message.setFrom(new InternetAddress("xx@sina.com"));
message.addRecipient(Message.RecipientType.TO,new InternetAddress("gaofei@landpage.com.cn"));
message.setSubject("这是测试标题");
message.setText("这是测试正文");
message.saveChanges();
Transport transport = ssion.getTransport("smtp");
transport.connect("smtp.sina.com.cn","xx","passwd");
transport.sendMessage(message, message.getAllRecipients());
transport.close();
